7th Grade Math 7.4(A)

Front

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

Back

d = rt, where d is distance, r is rate (speed), and t is time.

Front

If a car travels at 55 miles per hour, how far will it travel in 3 hours?

Back

d = 55 miles/hour * 3 hours = 165 miles.

Front

What does the variable 'd' represent in the equation d = 55t?

Back

'd' represents the distance traveled in miles.

Front

What does the variable 't' represent in the equation d = 55t?

Back

't' represents the time in hours.

Front

If Pamela rides her bike at a constant rate of 0.1 kilometers per minute, how far will she travel in 10 minutes?

Back

y = 0.1 km/min * 10 min = 1 km.

Front

What is the relationship between time and distance in a constant speed scenario?

Back

Distance is directly proportional to time when speed is constant.

Front

If a car travels 160 miles in 3 hours, what is its average speed?

Back

Average speed = total distance / total time = 160 miles / 3 hours = 53.33 miles/hour.

Front

What is a constant rate in the context of motion?

Back

A constant rate means the speed does not change over time.

Front

How do you convert minutes to hours?

Back

Divide the number of minutes by 60.

Front

If x represents time in minutes, what is the distance traveled in kilometers if x = 15 minutes at a rate of 0.1 km/min?

Back

y = 0.1 km/min * 15 min = 1.5 km.
