Question

A train moves at a constant speed of 75 km/hr.
(1) How far will it travelin 20 minutes?​

Answer 1

Answer:

25 km

Step-by-step explanation:

In 60 minutes a train travels = 75km

In 1 minutes a train travels = 75/60km

In 20 minutes a train travels = 75/60 × 20 km

= 25 km

Answer 2

ANSWER:

GIVEN:

INITIAL VELOCITY (U) = 75 KM/HR

TIME = 20 MINUTES = 0.33 HOURS

ACCELERATION = ZERO ( AS IT IS TRAVELLING WITH CONSTANT SPEED)

DISTANCE (S) = ?

FROM THE EQUATION, S = UT + 1/2 AT^2

BY SUBSTITUTING THE VALUES WE GET:

S = (75) (0.33) + 1/2 (0) (0.33)^2

S = (75) (0.33) + 0

S = 24.75 KILOMETRES

THEREFORE THE TRAIN TRAVELS 24.75 KILOMETRES IN 20 MINUTES.
