Given that,
Distance = 150 km
Speed of motorcyclist = 75 km/h
Speed of bus =60 km/h
Speed of truck = 50 km/h
Speed of bicyclist = 20 km/h
We need to calculate the average speed
Using formula of average speed

Put the value into the formula


We need to calculate the time
Using formula of speed


Where, D = total distance
t = time
Put the value into the formula


Hence, The time required to travel the entire distance is 2.93 hour.
