Motocycle = 2 hours
Bus = 2. 5 hours
Truck = 3 hours
Bicycle = 7.5 hours.

Explanation:

R = D/T R=DT or

T = D/R T=DR

Where RR = rate

Where DD = distance

Where TT = time

Motocycle's time = 150/75 = 215075=2

Bus's time = 150/60 = 2 1/215060=212

Truck's time = 150/50 = 3 15050=3

Bicycle's time = 150/20 = 7 1/215020=712
