constant speed 50s

1000÷50

=20

Answer 2

Hi there,

The question given by you was not clear enough. So, I have rewritten the question for you and have solved it accordingly. Hoping the required question to be as followed:  

Q. A bus is moving with a uniform speed of 20 m/s on a straight road. A police jeep wishes to catch the bus in exact 50 s. If the bus is at a distance 500 m ahead of police jeep. With what constant speed the jeep should move to chase the bus?

1) 25 m/s

(2) 30 m/s

(3) 40 m/s

(4) 35 m/s

Answer: 30 m/s

Explanation:

The bus is moving with a uniform speed, S₁ = 20 m/s

The time required by the police jeep to catch the bus = 50 s

Distance between the bus and the police jeep = 500 m

Let the constant speed of the jeep  be “S₂” m/s .

 

Since the bus and the police jeep is moving in the same direction, therefore,  

The relative speed = (S₂ – S₁) m/s

So,  

Relative Speed = (Distance traveled) / (time taken)  

⇒ (S₂ - 20) = 500 / 50

⇒ S₂ – 20 = 10

⇒ S₂ = 20 + 10

⇒ S₂ = 30 m/s

Thus, with a constant speed of 30 m/s, the jeep should move to chase the bus.
