Aran and anil are going to run in a race. Aran runs 7 mph while anil runs at 5 mph. They decide it would be fair if anil got a 1 hour head start. How far apart are they after 3 hours?

Answer: They are 41 miles apart after 3 hours.

Step-by-step explanation:

The speed at which Aran runs is

7 mph.

Distance = speed * time

If Aran runs for 3 hours, then the distance that he would cover is

7 * 3 = 21 miles

The speed at which Anil runs is

5 mph. They decide it would be fair if Anil got a 1 hour head start. This means that the total time that Anil spent running is 3 + 1 = 4 hours.

Distance covered by Anil in 4 hours is

5 * 4 = 20 miles

Therefore, the total distance covered after 3 hours is

21 + 20 = 41 miles
