Answer 2

Answer:

1. radius= 100m

circumference= 200pi

speed = distance/ time

speed = (200x22/7)/40

on calculating

speed = 110/7 = 15.71 m/s

when time = 2 min 20 sec = 140 s

distance= speed x time

distance = (110/7)*140

on calculating

distance= 2200m or 2.2km

Answer:

2. distance= 28m

time= 50 s

speed= distance/time

speed= 28/50= 14/25 m/s

distance2 = 32m

time 2 = 4 s

speed 2 = 32/4= 8m/s

average speed = (14/25+8)/2

                         = (14+200/25)/2

                         = (214/25)*2

                         = 428/25 = 17.12 m/s
