Three roads lead into a stadium's parking areas. Each road has four lanes (two in each direction) with a capacity of 1,000 vehicles/lane/hour. If 10,000 vehicles are expected for a game, how long will it take for all of them to enter the parking areas?

Option A

Explanation:

The complete question is

Three roads lead into a stadium's parking areas. Each road has four lanes (two in each direction) with a capacity of 1,000 vehicles/lane/hour. If 10,000 vehicles are expected for a game, how long will it take for all of them to enter the parking areas?

a) 2 hours

b) 1 hour

c) 1 hour and 40 minutes

d) 90 minutes

Solution

There are four lanes.

Capacity of one lane is equal to 1,000 vehicles/lane/hour.

Let us say that each lane will provide access to equal number of vehicles

Thus, each lane will allow 10,000/4 = 2500 vehicles per hour

Time taken by 2500 vehicles on road to reach parking is equal to 2.5 hours.

The nearest answer to this option A i.e two hours
