Week 2: Travel Time and Distance Quiz

A car travels from City A to City B at an average speed of 60 km/h. If the distance between the two cities is 240 km, how many hours does the trip take?

• 2 hours

• 3 hours

• 4 hours

• 5 hours

Answer explanation

To find the time taken for the trip, use the formula: time = distance / speed. Here, distance = 240 km and speed = 60 km/h. Thus, time = 240 / 60 = 4 hours. Therefore, the correct answer is 4 hours.

A cyclist rides from her home to the park at a speed of 15 km/h. If the distance between her home and the park is 9 km, how many minutes does the trip take?

• 30 minutes

• 36 minutes

• 45 minutes

• 60 minutes

Answer explanation

To find the time taken, use the formula: time = distance/speed. Here, time = 9 km / 15 km/h = 0.6 hours. Converting hours to minutes: 0.6 * 60 = 36 minutes. Thus, the trip takes 36 minutes.

A plane flies from New York to Los Angeles at an average speed of 900 km/h. If the distance between the two cities is 4000 km, how many hours does the flight take?

• 4 hours

• 4.5 hours

• 5 hours

• 5.5 hours

Answer explanation

To find the flight duration, divide the distance by the speed: 4000 km ÷ 900 km/h = 4.44 hours, which rounds to 4.5 hours. Thus, the correct answer is 4.5 hours.

A plane flies from New York to Los Angeles, a distance of 4500 kilometers. If the plane starts at 9:00 AM and flies at an average speed of 900 kilometers per hour, what time will it arrive at Los Angeles?

• 11:00 AM

• 12:00 PM

• 1:00 PM

• 2:00 PM

Answer explanation

The plane travels 4500 km at 900 km/h, taking 5 hours (4500/900). Starting at 9:00 AM, it arrives at 2:00 PM.

A runner runs around a track at a speed of 10 km/h. If the track is 400 meters long, how many minutes does it take the runner to complete one lap?

• 1.2 minutes

• 2.4 minutes

• 2 minutes

• 2.5 minutes

Answer explanation

To find the time taken to complete one lap, convert the speed to meters per minute: 10 km/h = 166.67 m/min. Then, divide the track length (400 m) by the speed: 400 m / 166.67 m/min = 2.4 minutes. Thus, the correct answer is 2.4 minutes.

A car travels from City A to City B at an average speed of 100 km/h. If the car takes 3 hours to complete the trip, what is the distance between the two cities?

• 250 km

• 300 km

• 350 km

• 400 km

Answer explanation

To find the distance, use the formula: Distance = Speed × Time. Here, Speed = 100 km/h and Time = 3 hours. Thus, Distance = 100 km/h × 3 h = 300 km. Therefore, the distance between City A and City B is 300 km.

A bicycle travels from home to school at a speed of 20 km/h. If the distance between home and school is 8 km, how many minutes does the trip take?

• 20 minutes

• 24 minutes

• 30 minutes

• 40 minutes

Answer explanation

To find the time taken, use the formula: time = distance/speed. Here, time = 8 km / 20 km/h = 0.4 hours. Converting hours to minutes: 0.4 * 60 = 24 minutes. Thus, the trip takes 24 minutes.

A train travels from City A to City B at an average speed of 120 km/h. If the distance between the two cities is 360 km, how many hours does the trip take?

• 2.5 hours

• 3 hours

• 3.5 hours

• 4 hours

Answer explanation

To find the time taken for the trip, use the formula: time = distance / speed. Here, time = 360 km / 120 km/h = 3 hours. Therefore, the correct answer is 3 hours.

A swimmer swims at a speed of 5 km/h. If the swimmer swims for 2.5 hours, what is the distance covered?

• 10 km

• 12.5 km

• 15 km

• 17.5 km

Answer explanation

To find the distance covered, use the formula: Distance = Speed × Time. Here, Distance = 5 km/h × 2.5 h = 12.5 km. Therefore, the correct answer is 12.5 km.

Dusty rides from home to school, a distance of 12 kilometers. If he starts at 7:30 AM and rides at an average speed of 15 kilometers per hour, what time will he arrive at school?

• 8:00 AM

• 8:18 AM

• 8:30 AM

• 8:45 AM

Answer explanation

Dusty rides 12 km at 15 km/h, taking 0.8 hours (48 minutes). Starting at 7:30 AM, he arrives at 8:18 AM. Thus, the correct answer is 8:18 AM.
