Question

an athlete completes one round of a circular trak of diameter 200 m in 40 s. what will be the distance covered and the displacement at the end of 2 minutes 20 s........... please give short answer ​

Answer 1

diameter of track =200m

so, radius =diameter/2

=200/2

=100m

time taken=40s

so...

circumference of circle=2πr

=2×3.14×100

=628m

so... distance covered in 1s=628/40

=15.7m

so.... distance covered in 2min 20s...

= distance covered in 140s

=15.7×140

=2198m.....

Answer 2

Just imagine yourself running in the track...
