Time and Distance Practice Test 2 with solutions

Question : 30 of 40

Marks: +1, -0

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

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

Validate

Solution:

Let x km/hr be the required speed of the train; then

x× {40}/{60}

48 × {50}/{60}

∴ x =

{48××50}/{40}

= 60 km/hr
