Numerical Ability
A super fast bus of KSRTC starting from 'Trivandrum' and reaches 'Attingal' in 45 minutes with an average speed of 40 km/hr. If the speed is increased by 10 km/hr how much time it will take to cover the same distance?(a) 34 minutes (b) 36 minutes (c) 38 minutes (d) 40 minutes

Answer is 36 mins We can approach the problem as followsFirst we have to find the distance we can do so byspeed = 40Time = 45 minshence dt = speed * ttdt = 2 * (15)dt = 30Now the speed can be increased by 10 now the speed is 50tt = dt/speedtt = (30/50) * 60tt = 0.6 * 60tt = 36.0

B) 36 mind=s*ts=40 km/hr=40/60km/mint=45mind=(4/6)*45=30kmnow increased speed= 50 km/hr=50/60 km/mind=30 kmt=d/s = 36 min
