Barry's unit rate is 15 minutes per mile and Robin's unit rate is 12 minutes per mile

The unit rates of Barry and Robin

We have:

Barry

Distance = 2 miles

Time = 30 minutes

Unit rate = Time/Distance

Unit rate = 30 minutes/2 miles

Unit rate = 15 minutes per mile

Robin

Distance = 3 miles

Time = 36 minutes

Unit rate = Time/Distance

Unit rate = 36 minutes/3 miles

Unit rate = 12 minutes per mile

Hence, Barry's unit rate is 15 minutes per mile and Robin's unit rate is 12 minutes per mile

Who walk faster?

The unit rates mean that:

  • Barry covers 1 mile in 15 minutes
  • Robin covers 1 mile in 12 minutes
