Answer 1

Given:

a.) Ishi walked a total of 2 1/2 miles on a treadmill.

b.) He walked at a constant rate of 4 miles per hour.

For us to be able to determine how long, in minutes, Ishi walked on the treadmill, we will be using the following formula:

`\text{ Total distance Ishi walked }/\text{ Constant rate x Equivalent in minutes}`

We get,

`\text{ 2 }(1)/(2)\text{miles }/\text{ 4 }\frac{\text{miles}}{\text{ hour}}\text{ x }\frac{\text{ 60 minutes}}{1\text{ hour}}`

Therefore, the answer is letter B.
