Question
A man walking at a speed of 30kmph reaches from his house to office at 5pm. Next time at a speed of 60kmph reaches from his house to office at 2pm find the distance of his office from home?Options180km120km140km160km
Solution
To solve this problem, we need to understand that the difference in arrival times is due to the difference in speeds.
-
First, let's find the difference in arrival times. If the man arrives at 5pm when walking at 30kmph and at 2pm when walking at 60kmph, the difference is 3 hours.
-
Now, we know that speed = distance/time. We can rearrange this formula to find distance = speed * time.
-
If we substitute the values we have into this formula, we find that distance = 60kmph * 3 hours = 180km.
So, the distance from his house to his office is 180km.
