Distance, Speed, and Time Problems

Mr. Kwik's video tutorial covers the concept of speed and measurement units, focusing on the formula distance = rate x time. The lesson includes examples of calculating rate, distance, and time in various scenarios, such as a runner's speed, a car's travel distance, and a construction zone. The video also explores Chris Johnson's 40-yard dash, demonstrating how to calculate speed and distance over time.

What is the formula used to calculate distance when speed and time are known?

• Distance = Speed + Time

• Distance = Speed / Time

• Distance = Time / Speed

• Distance = Speed x Time

If a runner covers 50 feet in 8 seconds, what is their speed in feet per second?

• 6 feet per second

• 5 feet per second

• 8 feet per second

• 6.25 feet per second

A car travels at 65 miles per hour for 3 hours. How far does it travel?

• 130 miles

• 200 miles

• 195 miles

• 180 miles

What is the distance of a construction zone if a car travels at 50 miles per hour for 0.25 hours?

• 20 miles

• 12.5 miles

• 15 miles

• 10 miles

Chris Johnson ran a 40-yard dash in 4.24 seconds. What is his speed in yards per second?

• 8.5 yards per second

• 9 yards per second

• 10 yards per second

• 9.43 yards per second

How many yards would Chris Johnson run in one minute at a constant speed of 9.43 yards per second?

• 565.8 yards

• 600 yards

• 550 yards

• 580 yards

If Chris Johnson maintains his speed for an hour, how many yards will he cover?

• 33,948 yards

• 32,000 yards

• 30,000 yards

• 35,000 yards

What is the conversion factor from minutes to hours?

• 90 minutes in an hour

• 60 minutes in an hour

• 45 minutes in an hour

• 30 minutes in an hour

If a car travels at a constant speed, what happens to the distance if the time is doubled?

• Distance remains the same

• Distance is halved

• Distance is doubled

• Distance is tripled

What is the speed of a vehicle if it covers 100 miles in 2 hours?

• 50 miles per hour

• 40 miles per hour

• 55 miles per hour

• 60 miles per hour
