Second friend walks faster

Solution:

Two friends workout on the treadmill

To find who walked datser, let us first find the unit rate

Unit rate = miles walked in 1 hour ( miles per hour )

One friend walked 2 miles in of an hour

Therefore,

Thus unit rate of first friend is 2.67 miles per hour

The second friend walked mile in 30 minutes

First convert the mixed fraction to improper fraction

Convert 30 minutes to hours

unit rate of second friend > unit rate of first friend

3.5 > 2.67
