Question

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

Answer 1

Speed of man = 5 m/s = 18 km/h

Time = 1 hour 20 minutes = 1/3 hour

Distance = Speed × Time

= 18 km/h × 1/3 hour

= 6 km

The man runs 6 km in 1 hour and 20 minutes.

Answer 2

24 KILOMETERS

Step-by-step explanation:

5 m/s = 5 * (18 / 5) km/hr

==> 5 m/s = 18 km / hr

1 hr 20 mins = 1 hr + 20/60 hr = 1 1/3 hr = 4 / 3 hrs

In 1 hr, the man runs 18 km

In 4/3 hrs, the man runs (4 / 3) * 18 = 24 km
