Question

A scooterists sees a bus 1km ahead of him moving with a velocity of 10m/s .with what speed ,the scooterist shoukd move so as to overtake the bus in 100s.

Answer 1

Hey mate!

Here's your answer!!

Given,

t = 100s,
s = 1000m;
v = 10m/s.

But this is the relative speed with respect to the bus

Vs - actual velocity of scooter;
Vb = velocity of bus;
v = relative velocity of scooter wrto bus.

v = Vs-Vb as both busand scooter are moving in same dir.

10 = Vs-10;
So,
Vb = 20m/s

Hope it helps you!

Answer 2

scooterist velocity is 20 m/s
