Question

(11) How much time would it take to cover 200 metres?
6. A swimming pool is 50 metres long. A boy can swim across the length
return to his starting position in 5 minutes. What is his swimming
km/h?​

Answer 1

AnswEr:-

→As he returns back total distance covered is 2 times the length of swimming pool.

⇒ distance =2×50 = 100 m =100/1000= 0.1 km

⇒ time taken =5 min =5/60 = 0.08 hrs

→ speed =distance/time taken

⇒speed = 0.1/ 0.08 = 1.25 km/hr
