Question

Claire is cycling at a speed of 12 miles per hour. Han is cycling at a speed of 8 miles per hour. If they start at the same position, chosen at zero, and bike in straight opposite directions, what will the distance between them be after 45 minutes?

Answer 1

180 miles.

Explanation:

First, we have to find out how far Claire is after 45 minutes:

12 x 45 = 540

Now, we need to find out how far Han is after 45 minutes:

8 x 45 = 360

Lastly, we need to subtract how far Claire went by how far Han went:

540 - 360 = 180

Final answer:

The distance between Claire and Han after 45 minutes will be 180 miles.

Hope this helped! Have a nice day!

Answer 2

45 minutes is 3/4 of an hour, so find 3/4 of 12.

Divide 12 by 4 to get 1/4 of 12. That is 3.

3/4 is 3 of those, so multiply it by 3 to get 9.

So, she will have biked 9 miles.
