Question

A free bus service operates throughout the day around Brelney City Centre. The bus starts from the Railway Station, then stops successively at the Castle, the Shopping Centre, the Park and the Stadium, before returning to the Railway Station. The journey time for each section of the circuit is 5 minutes.

The first departure of the day from the Railway Station is at 09:15. Each time the bus arrives back at the Railway Station it waits for 10 minutes before setting off again.Bart will be the driver for the first 4 circuits tomorrow.At what time will Bart arrive back at the Railway Station for the final time tomorrow?
A 11:25
B 11:35
C 11:45
D 11:55

Answer 1

Explanation:

Each circuit takes 25 minutes (5 destinations times 5 minutes) plus the 10 minute wait at the Railway Station. So the entire circuit is 35 minutes with the wait. Bart drives 4 circuits - 4 times 35 minutes is 140 minutes.

140 minutes equals 2 hours and 20 minutes.

Add 2 hrs and 20 minutes to 9:15 and the sum = 11:35

The answer is B - 11:35

Answer 2

The bus journey takes 25 minutes (5 minutes per stop x 5 stops). The bus leaves the Railway Station every 10 minutes (the wait time between circuits).

The first departure is at 09:15, so the bus will arrive back at the Railway Station at:

09:15 + 25 minutes = 09:40

Bart will drive the bus for 4 circuits, so the bus will arrive back at the Railway Station for the final time at:

09:40 + (4 x 25 minutes + 4 x 10 minutes) = 09:40 + 130 minutes =

11:50.

So the final arrival time will be D 11:55.
