Question

A distance of 150 km was covered by a motorcyclist traveling at a average speed of 75 KM/h by a bus 60 km/h a truck at 50 km/h and a bicyclist at 20 km/h how much time did it require to travel the entire distance

Answer 1

Motorcyclist: 2 hours

Bus: 2.5 hours

Truck: 3 hours

Bicyclist: 7.5 hours

Explanation:

Answer 2

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

Explanation:

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

`v_(avg)=(v_(m)+m_(b)+m_(t)+m_(bi))/(4)`

Put the value into the formula

`v_(avg)=(75+60+50+20)/(4)`

`v_(avg)=51.25\ km/h`

We need to calculate the time

Using formula of speed

`v=(D)/(t)`

`t=(D)/(v)`

Where, D = total distance

t = time

Put the value into the formula

`t=(150)/(51.25)`

`t=2.93\ hour`

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