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

they built 2 2/3 km or approximately 2.67 km of road each day.
