Question

a train travelling at uniform speed takes 10 hours to cover 1200 km. express it in km/h and m/sec​

Answer 1

Explanation:

A train, travelling at uniform speed takes 10 hours to cover a distance of 1200 km. Express its speed in km/h and m/s. (Ans: 120 km/h, 33.3 m/s)

Answer 2

Explanation:

Given that:-

(Distance) d = 1200km/h

(time) t = 10 hr

we know that:-

speed = Distance/time ➡️ S = d/t

S = 1200/10

S= 120 km/h

For convert km/h to m/s always multiply 5/18

S = 120×(5/18)

S= 33.3m/s.

1km = 1000 m

1h = 60 min

1min = 60sec

1000/(60×60) = 5/18
