Answer:
The time required to travel the entire distance is 2.93 hour.
Step-by-step 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
[tex]v_{avg}=\dfrac{v_{m}+m_{b}+m_{t}+m_{bi}}{4}[/tex]
Put the value into the formula
[tex]v_{avg}=\dfrac{75+60+50+20}{4}[/tex]
[tex]v_{avg}=51.25\ km/h[/tex]
We need to calculate the time
Using formula of speed
[tex]v=\dfrac{D}{t}[/tex]
[tex]t=\dfrac{D}{v}[/tex]
Where, D = total distance
t = time
Put the value into the formula
[tex]t=\dfrac{150}{51.25}[/tex]
[tex]t=2.93\ hour[/tex]
Hence, The time required to travel the entire distance is 2.93 hour.
