Question

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

Answer 1

The problem gives a distance with a fraction (not a decimal); there is absolutely no reason to convert it to a decimal.

 

In 4 days, Val walks:

     4*(2 3/5) miles

     4*(13/5) miles           [convert to improper fraction]

      52/5 miles

       10 2/5 miles             [convert to mixed number]

 

Compare that to Bill, who runs 10 miles every 4 days.

 

Val runs a greater distance.

Answer 2

In 4 days, Val has gone 4*2.6 = 10.4 mi and Bill only 10 mi.  Val covers a greater distance.
