Question

A boy covers 50 km in 2 hours. In 40 min he will cover.
​

Answer 1

Step-by-step explanation:

if he covers 50 in 2 hour

1 hour = 60×1 min

= 60×2

= 120 min

120m/50km

1min = 1× 60 sec

= 120×60

= 2400 sec

2400sec / 50000 metre

per second = 50000/2400

= 20.83 metre

60 sec = 20.83 × 60

1 min = 1249.8 metre

40 min = 1249.8 × 40

= 49992 metre

1 metre = 1/1000

= 49992/ 1000

= 49 km 992 m
