Question
A bus covers a distance of 10 km in 12 minutes. If its
speed is reduced by 25 km/h, then what time (in minutes) will it take to cover the same distance?Solution
Distance covered by bus 10 km in 12 min. As we know, Speed = Distance/Time Speed of bus = 10/(12/60) = 50 km/hr New speed of bus = 50-25 = 25 km/hr  Time to cover 10 km distance with a speed of 25 km/hr = 10/25 x 60 = 24 min
