Question

How long does a car traveling at 70 mph take to travel 88 miles, in hours

Answer 1

So,

Obviously, the car will travel 70 miles in one hour. So after one hour, the car will have traveled 70 miles. That leaves 18 miles.

The time it will take for the car to go another 18 miles will be 18 divided by 70.

`(18)/(70)`

Simplify.

`(2*3*3)/(2*5*7)`

`(3*3)/(5*7)`

`(9)/(35)`

Divide.
≈ 0.25714

So a car traveling at 70 mph will take approximately 1.25714 hours or 1.26 hours to travel 88 miles.
