Answer :-

 V{bi} = 26.66 m/s

Given :-

velocity of bus is = 10 m/s

Distance b/w them is 1 km

t = 60s

To find :-

The velocity required to overtake the bus.

Solution:-

Let  V_b and  V_{bi} be the velocity of the bus and bike respectively.

Relative Velocity with respect to bus :-

 V = \dfrac{1000}{60}

 V = 16.66 m/s

Since,

They are moving in the same direction.

 V = V_{bi} - V_{b}

 16.66 = V{bi} - 10

 16.66 +10 = V{bi}

 V{bi} = 26.66 m/s

hence,

The required velocity to overtake the bus in 60 s will be 26.66 m/s.

hello there

Explanation:

Question: A bus moves with velocity 10m/s 1km away from a bike who wishes to overtake the bus in 60s what should be his velocity?

To find : The required velocity of the bike to overtake the bus.

Solution:

Given:

Speed of the bus = 10 m/s

Distance between them = 1 km

Also 1 km = 1000 m

Here,

Let the speed of the bike be = x m/s

[ As, According to the condition ]

Relative speed = (x-10) m /s

We ,know that :

 Distance = Speed \times Time

Putting their respective values in the formulae

Thus,

1000 m = (x - 10) ×60

1000 m = 60x - 600

(1000 + 600 ) m = 60x

60 x = 1600 m

x = (1600/60) m/s

x = 26.67 m/s

_____________________________

So, The velocity of the bike must be 26.67 m/s to overtake the bus in 60s.
