Question

A car travels420 miles in 8 hours the car continues at the same rate how far will it travel in 12 hours

Answer 1

First you find how many miles the car travels per hour, to do so you can divide 420 miles by 8 hours:

420 miles/8 hours = 52.5 miles/hr

Now that you know the car travels 52.5 miles per hour, you can multiply it by 12 to find out how many miles the car travels in 12 hours.

52.5 · 12 = 630

The car travels 630 miles in 12 hours

Answer 2

12 hours is 4 hours more than 8 hours.

4 hours is half of 8 hours.

If it traveled 420 miles in 8 hours, it will travel half of that in 4 hours, or 210 miles.

In 12 hours it travels 8 hours plus 4 hours, so it travels 420 miles plus 210 miles which is 630 miles.

Answer: 630 miles
