<PRE><B>Question 867925</B>
 Please help me solve this problem. 
If it takes a car wash 2 hours and 10 minutes to wash 57 cars, find the time needed to wash 200 cars. Answer in mixed hours and minutes, rounded to the nearest minute.
----
time/cars = time/cars
-----
t/200 = 130 min/57 cars
--------------------------------
time = 200[130/57]
time = 456.14 min = 7.602 hrs = 7hr +0.602(60)min = 7hr 36 min
