A bus is moving with a speed of 10ms−1 on a straight road. A scooterist wishes to overtake the bus in 100s. If the bus is at a distance of 1 from the scooterist, with what speed should the scooterist chase the bus ?
Answers
Explanation:
Given:
Time(t)= 100 s , distance (s)=1km= 1000m
Vb=10m/s (relative speed with respect to the bus)
Velocity (V)=distance /time = 1000/100= 10m/s
Vs= velocity of scooter, Vb=velocity of bus
V = Vs-Vb (both bus & scooter are moving in the same direction)
10= Vs-10
10+10 = Vs
20=Vs
Vs=20m/s

The velocity with which Given:
Time(t)= 100 s , distance (s)=1km= 1000m
Vb=10m/s (relative speed with respect to the bus)
Velocity (V)=distance /time = 1000/100= 10m/s
Vs= velocity of scooter, Vb=velocity of bus
V = Vs-Vb (both bus & scooter are moving in the same direction)
10= Vs-10
10+10 = Vs
20=Vs
Vs=20m/s
--------------------------------------------------------------------------------------------
The velocity with which scooterist should chase the bus is20m/s
