IBPS SO Prelims Exam Model Paper 4

Length of car = 3 m
Length of truck = 17 m
Relative distance to be covered by the car = 3 + 17 = 20 m
Let speed of car be s m/s
Speed of truck = 54 km/hr = 15 m/s
Speed of car should be greater than that of truck for it to overtake the truck
Relative speed of car w.r.t truck = (s – 15)
Time to overtake = 5 sec
Speed =

s = 19 m/sec
The minimum speed of car should be 19 m/s
