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
