A car is traveling at a rate of 57 miles per hour. What is the car’s rate in miles per minute? How many miles will the car trave

Hello!

We have to find how fast the car goes a minute

To find this we can do 57/60 since the car goes 57 miles an hour and there are 60 minutes in an hour

This gives us 0.95 miles a minutes

Then we do how fast the car goes a minute by the amount of minutes

So 0.95 * 15 = 14.25

The car goes 14.25 miles in 15 minutes

Hope this helps!
