Walking at the rate of 4 km an hour, a man covers a certain distance in 3 hours 45 minutes. If he covers the same distance on cycle, cycling at the rate of 16.5 km/hr, the time taken by him is :
Walking at the rate of 4 km an hour, a man covers a certain distance in 3 hours 45 minutes. If he covers the same distance on cycle, cycling at the rate of 16.5 km/hr, the time taken by him is :
[A]45.55 minutes
[B]54.55 minutes
[C]55.44 minutes
[D]55.45 minutes
54.55 minutes
Distance covered on foot $latex = 4\times 3\frac{3}{4}km = 15km&s=1$
∴ Time taken on cycle $latex = \frac{Distance}{Speed} = \frac{15}{16.5}hour&s=1$
$latex = \frac{15\times 60}{16.5}minutes&s=1$
$latex = 54.55 minutes$
Hence option [B] is correct answer.
