Answer:

2.4 hours

Step-by-step explanation:

Let x = hours riding on bike

One cyclist covers 10 miles for every hour, so multiply x by 10 like this: 10x

Other cyclist covered 15 miles for every hour, so multiply x by 15 like this: 15x

They will both add up to 60

10x + 15x = 60

25x = 60

Divide both sides by 25

25x/25 = 60/25

x = 2.4
