Question

. A swimming pool is 100 m long. A boy can swim across the length of the pool and then return to his starting position in 8 minutes. What is his speed in km/ hour?


Explain briefly ​

Answer 1

Answer:

6 km/hour

Step-by-step explanation:

length= 100

swimming time =8 minutes

total distance covered= 100 × 8 = 800m  

speed formula = Distance ÷ time  

so 800/1000×60/8  

4/5×15/2

60/10=6km/per hour
