Walking at the rate of 4 kmph a man cover certain distance in 2 hr 45 min. Running at a speed of 16.5 kmph the man will cover the same distance in. ____ min
Question
Solution
First, we need to find out the distance the man covered walking at 4 kmph for 2 hours and 45 minutes.
- Convert the time to hours: 2 hours 45 minutes = 2.75 hours
- Use the formula distance = speed * time: 4 kmph * 2.75 hours = 11 km
Next, we need to find out how long it would take the man to cover the same distance running at 16.5 kmph.
- Use the formula time = distance / speed: 11 km / 16.5 kmph = 0.6667 hours
- Convert the time to minutes: 0.6667 hours * 60 minutes/hour = 40 minutes
So, the man will cover the same distance in 40 minutes running at a speed of 16.5 kmph.
