Question

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

Answer 1

the fox runs rhe fastest because the rabbit runs 35 miles per hour and thats a lot but rhw fox runs 21 in half a hour that's short so its the fox

Answer 2

You can write it as:
Rabbit = 35mi in 1 hour
Fox = 21mi in 0.5 hours

To change the 0.5 hours into 1 hour, we need to multiply it by 2 so...
21*2 = 42

Then we can calculate the difference and write the answer:
42-35 = 7

The Fox runs faster than the rabbit by 7 miles an hour.

Hope this helps! :)
