Val walks 2 3/5 miles each day. bill runs 10 miles once every 4 days. in 4 days, who covers the greater distance?

So if Bill runs 10 miles in those 4 days then we need to find out Val's.

2 and 3/5. Well, we already know 2*4=8
so 0.6 (which is 3/5) multiplied by 4 is 2.4.
8+2.4=10.4

So here are the results for the distance covered in 4 days :

Val = 10.4 miles
Bill = 10 miles

Therefore, I think Val covers the most distance in 4 days.
Hope I helped :)
