Back

Average speed is the total distance traveled divided by the total time taken. It is measured in miles per hour (mph) or feet per minute (ft/min).

Front

How do you calculate average speed?

Back

Average speed = Total Distance / Total Time.

Front

If Jennifer drives 265 miles in 5 hours, what is her average speed?

Back

53 mph.

Front

What is the formula to find speed?

Back

Speed = Distance / Time.

What is the speed of a sloth that moves 3/8 of a foot in 3/4 of a minute?

Back

1/2 ft/min.

Front

How do you convert a fraction to a speed in feet per minute?

Back

Multiply the distance by the rate of time conversion (e.g., multiply by 60 for minutes).

Front

What does a decrease of 20% mean in terms of price?

Back

A decrease of 20% means the new price is 80% of the original price.
