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
