Front

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

Back

The formula is d = st, where d is distance, s is speed, and t is time.

Front

If a car travels at a speed of 50 miles per hour, how far will it travel in 2 hours?

Back

d = 50t = 50 * 2 = 100 miles.

Front

What does the slope of a distance-time graph represent?

Back

The slope represents the speed of the object.

Front

What is the unit of speed in the context of distance and time?

Back

The unit of speed is typically miles per hour (mph) or feet per minute (ft/min).

Front

How do you convert hours to minutes?

Back

Multiply the number of hours by 60.

Front

If a car travels 120 feet in 5 minutes, what is its speed in feet per minute?

Back

Speed = distance/time = 120 feet / 5 minutes = 24 feet per minute.

Front

What is a mixed number?

Back

A mixed number is a whole number combined with a fraction, such as 3 1/2.

Front

How do you convert a mixed number to an improper fraction?

Back

Multiply the whole number by the denominator, add the numerator, and place over the original denominator.

Front

If George can build 3 2/3 sections in 5 1/2 hours, how many sections can he build in 1 hour?

Back

He can build 3 2/3 sections in 5 1/2 hours, which is approximately 0.67 sections per hour.

Front

What is the process to solve for time when distance and speed are known?

Back

Use the formula t = d/s, where t is time, d is distance, and s is speed.
