Question

converting Between compound unitsA car is traveling at a rate of 57 miles per hour. What is the car's rate in mlles per minute? How many miles will the car travel in 5 minutes? Do not round youranswers.

Answer 1

Convert miles per hour to miles per minutes, we can note that:

`1hour=60\text{minutes}`

Then:

`(mi)/(h)=(mi)/(60\min )`

Thus, to find the rate of miles per minutes, we divide the velocity by 60:

`57(mi)/(h)=(57)/(60)(mi)/(\min )=0.95(mi)/(\min)`

That's the answer to the first question. To find the miles traveled in 5 minutes, since we have the ratio in minutes we need to multiply the ratio by the time:

`0.95(mi)/(\min)\cdot5\min =4.75mi`

That's the answer to the second question.
