Q.9
Trucks (10m long) and cars (5 m long) go on a single lane bridge. There must be a gap of atleast 20 m after each truck and a gap of atleast 15m after each car. Trucks and cars travel at a speed of 36 km/h. If cars and trucks go alternatively, what is the maximum number of vehicles that can use the bridge in one hour?
A. 1440
B. 1200
C. 720
D. 600
Explaination / Solution:

Given speeds both car & Truck = 36 km/hour
They travel in 1 hr = 36 km = 36000 m.

Maximum no.of vehicles than can use the bridge
in1hour = (36000m/50m) = 720sets = 720 × 2 = 1440vechicles
Alternate method
Length of truck + gap required = 10+20 = 30m
Length of car + gap required = 5+15 = 20m
Alternative pairs of Truck and car needs 30+ 20 = 50 m.
Let 'n' be the number of repetition of (Truck + car) in 1 hour (3600 sec).
Givenspeed = 36km/hr = 10m/sec
(50m × n)/(3600sec) = 36 km/hr
(50n/3600)m/sec = 10 m/sec
n = (36000/50) = 720 (Truck + car)
So, 720 (Truck + car) passes = 720 × 2 = 1440vehicles
