A train takes 2 hours to travel from Ajmer to Jaipur, which are 130km apart. How much time will it take to travel from Delhi to Bhopal which are 780km apart if the train is travelling at the uniform speed?

Speed = …(i)

Distance covered Ajmer to Jaipur = 130 km

Time taken = 2 hours

Using (i)

Speed = = 65 km/hour …(ii)

Speed is uniform

Let the time taken to cover distance between Delhi and Bhopal be ‘a’

Distance between Delhi and Bhopal = 780 km

Using (i) and (ii)

⇒ 65 =

⇒ a =

Divide numerator and denominator by 5 we get

⇒ a = = 12 hours

Time to travel from Delhi to Bhopal is 12 hours
