Marks: +1, -0

A train covers a distance in 50 minutes if it runs at a speed of 48 km/hour on an average. The speed at which the train must run to reduce the time of journey to 40 minutes will be :

50 km/hr
55 km/hr
60 km/hr
70 km/hr

Validate

Solution:

Here, x ×

{40]/{60}

= 48 ×

{50}/{60}

∴ x =

48 × 5/4

= 60 km/hr
Hence, required speed = 60 km/hr
