Question

A swimming pool is 20m wide and the steps to enter the water is at the
corner. A person enters into the water from the steps at 5 PM and swims 30
times back and forth along the pool and finally leaves the pool at 5:20 PM by
climbing the same steps. What is the average speed of the swimmer?

Answer 1

Answer:

Step-by-step explanation:

TIME = 20 MINS (BECAUSE STARTING TIME = 5:00PM AND ENDING TIME : 5:20 PM)

DISTANCE = 20 M

AVERAGE SPEED = TOTAL DISTANCE / TOTAL TIME

AVERAGE SPEED = 20/20

AVERAGE SPEED = 1m/s

hope this helps u

Answer 2

Answer:

dist =20m×30 rounds =600m

time=20min

Speed =dist/time

speed=600/20m×60{converting to seconds}

speed=600/1200

speed =0.5meter/per seconds
