Question

A girl swims in a 90m long pool. She covers
180m in I min by swinning from one end
to the other and back along the
same straight path. Find average speed​

Answer 1

Answer:

Average speed of the girl is approximately 0.02 m/s.

Explanation:

Distance = 90*2 = 180m

Time = 180min = 180*60 = 10800 seconds

$Average Speed = \frac{Total Distance}{Total Time}$

$Average Speed = \frac{180}{10800}$

$Average Speed = 0.016m/s$

$Average Speed = 0.02m/s$
