Question
A man covers a certain distance in 3 hours 36 minutes if he walks at the rate of 5 km/hr. If he covers the same distance on cycle at the rate of 24 km/hr, then the time taken by him in minutes is?Options40505545
Solution
First, we need to find the distance covered by the man. We know that distance = speed * time.
Here, the speed of the man is 5 km/hr and the time is 3 hours 36 minutes. But we need to convert the time into hours completely.
36 minutes = 36/60 = 0.6 hours.
So, the total time is 3.6 hours.
Now, we can find the distance = 5 km/hr * 3.6 hr = 18 km.
Next, we need to find the time taken to cover the same distance on a cycle. We know that time = distance / speed.
Here, the speed of the cycle is 24 km/hr.
So, the time = 18 km / 24 km/hr = 0.75 hours.
But the question asks for the time in minutes.
So, we convert 0.75 hours into minutes.
0.75 hours = 0.75 * 60 = 45 minutes.
So, the time taken by him to cover the same distance on a cycle is 45 minutes.
