Question

If a man runs at 5 meter per second, how many kilometer does he run in 1 hour 20 minutes ?

Answer 1

Answer:

24km

Step-by-step explanation:

distance covered by the man in 1 min= 5*60m= 300m

distance covered by the man in 1 hour= 300*60m=18,000m

distance covered in 20 mins= 300*20= 6,000m

distance covered in 1 hour and 20 mins= 18000+6000m= 24,000m

24000m= 24000/1000km= 24km

Answer 2

The distance traveled by the man is 24 km.

Given,

The speed of the man is 5 m/s.

To Find,

The distance(in Km) traveled by the man in 1 hour 20 minutes.

Solution,

First of all, we will convert the given time in seconds\

1 minute = 60 seconds

20 minutes = 20*60 = 1200 seconds

Now,

1 hour = 3600 seconds

So,

1 hour 20 minutes = 3600+1200 = 4800 seconds

Using the formula

Speed = distance/time

5 = distance/4800

Distance = 24000 meters

So, distance in kms will be 24000/1000 = 24 km.

Hence, the distance traveled by the man is 24 km.
