Question

A rabbit runs 35 miles per hour. A fox can run 21 miles in half an hour. Which animal is faster, and by how much?

Answer 1

The Fox, by 7 Miles per hour

Explanation:

The rabbit runs 35 Miles per hour

The Fox runs 21 in half an hour

1 hour - 30 minutes = 30 minutes meaning we have to double the foxes miles

21 x 2 = 42

42>32

To find out by how much do 42-32 and we get 7 Miles per hour.

Answer 2

The fox can run faster by a factor of 7 miles per hour

Explanation:

If the fox runs 21 miles in half of an hour, that means that by multiplying the fraction 21miles/0.5hours by 2/2 you can find that the fox runs 42 miles per hour, 7 miles per hour faster than the rabbit.
