Question:

10,000 cars move from A to B between 8:00 a.m. and 9:00 a.m. There are three different roads connecting A to B. The time it takes for a car to go from A to B by the three alternatives roads are 5 + 3h, 6 + 2h and 11 + h respectively, where h is the number of thousands of cars on the road. How long will it take to go from A to B? (Hint: use the equilibrium condition)

A. 12 minutes

B. 17 minutes

C. 14 minutes

D. 41 minutes

Least Costly Method:

When several methods are being compared on a cost basis, the most efficient method can be determined by using the equations for the time taken by each method and then using them simultaneously to obtain the best value of the variable, which will minimize the time of one method.
