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

Pachacha [2.7K]

Answer:

Step-by-step explanation:

The fox is faster. Because he is a fox.

Also because he can (assuming he doesn't fatigue or get caught by hounds in the second half of the hour) run 42 miles in 1 hour.

The rabbit runs 35 miler per hour.

Velocity = Distance/time

Fox velocity = 21 miles/0.5 hour

Dividing by 0.5 is the same as multiplying by 2, so...

Fox velocity = 42 miles/hour
