Question

An electric train is moving with a speed of 120km/h how much distance it travel in 30s

Answer 1

Hey there !

Thanks for the question !

Solution :

Given that the electric train travels at 120 km/hr

120 km in 60 min so it means that 120 km in 3600 seconds. 3600 seconds because 1 hour has 3600 seconds.

So 120 km : 3600 sec :: x : 30 sec

Product of Extremes = Product of Means

=> 120 * 30 = 3600 * x

=> 3600 = 3600 x

=> x = 3600 / 3600

=> x = 1 km

Hence the electric train will travel 1 km.

Hope my answer helped !
