Problema Solution

A construction crew has just finished building a road. The road is 10 km long. If the crew work for 3 3/4 days, how many kilometers of role did they build each day?

Answer provided by our tutors

we will assume that the crew built equal length of road each day


x = km of road built each day


3 3/4 = (3*4 + 3)/4 = 15/4


(15/4)x = 10


by solving we find:


x = 8/3 km


x = 2 2/3 km


x = 2.67 km
