Question

Margarit drove her friends to a movie. She drove for 30 minutes at 10 miles per hour in heava

traffic, and then she drove for 15 minutes at 40 miles per hour. How far did she travel in those
45 minutes?

Answer 1

15 miles

Explanation:

So to find how many miles she traveled in the first 30 minutes going 10 miles per hour we divide 10 by 2. This is because 30 minutes is half of an hour therefore the distance she goes is 5 miles.

To find how much she drove for the last 15 minutes at 40 miles per hour we multiply 1/4 by 40 miles. We multiply 1/4 by 40 because 15 minutes is a quarter of an hour. The distance she goes is then 10 miles in 15 minutes.

Now, add both 5 miles from the first 30 minutes and 10 miles from the last 15 minutes to get the answer of 15 miles.

Therefore, Margarit drove 15 miles in the 45 minutes.

I hope this helps!!
