Respuesta :

Steven ran 15 miles in 8 minutes.

so, the unit rate = distance over the time

So, the unit rate for Steven = 15/8 = 1.875 miles/minutes

Jackson ran 20 miles in 11 minutes

so, the unit rate for Jackson = 20/11 = 1.818 miles/minutes

By comparing the numbers 1.875 and 1.818

So, 1.875 > 1.818

So, the unit rate of Steven > unit rate of Jackson

so, the faster is Steven
