Question

if you want to cover a circular track of radius 20 m in 1 minute with what average speed you will run to do so is it possible for you to attend this speed

Answer 1

Answer:

Explanation:

HERE IS UR ANSWER....

GIVEN THAT =

RADIUS = 20 M\

TIME = 1 MINUTE = 60 SECONDS

AV, SPEED == TOTAL DISTANCE/ TOTAL TIME TAKEN

HERE THERE IS CIRCULAR TRACK SO THE DISTANCE TRAVELLED WILL BE THROUGH CIRCUMFERENCE THAT IS 2 PIE R

THEREFORE

AV. SPEED = 2 PIE 20/ 60

= 40PIE /60

SO THE AV SPEED IS

= 2/3 PIE M/S

PLZ MRK BRAINLIEST IF HELPED..

Answer 2

Explanation:

avg. speed = total distance/ total time

total distance= 2πr

=2×22/7×20

= 880/7

total time= 60 second

= 2.95m/s
