Time spent = End time - Start time. For example, if John starts hiking at 11:30 AM and finishes at 3:30 PM, he spends 4 hours hiking.

Front

If Amy rides her bike 4 miles in 30 minutes, how do you find the distance she rides per minute?

Back

Divide the total distance by the total time: 4 miles ÷ 30 minutes = 0.13 miles per minute.

Front

What is the unit rate of speed?

Back

Front

How do you convert a total cost to a unit price?

Back

To convert a total cost to a unit price, divide the total cost by the number of units. For example, if 10 apples cost $5, the unit price is $5 ÷ 10 = $0.50 per apple.

Front

How can you express a unit rate as a fraction?

Back

A unit rate can be expressed as a fraction where the numerator is the quantity of interest and the denominator is 1. For example, 60 miles per hour can be written as 60/1.
