Question

Which is the best estimate of the runners average speed in meters per second

Answer 1

given,

8.25 as time around a track

with time 1119.803 seconds

402.3 metres as lap around track

first of up lets find the distance covered

that is,

8.25 x 402.3

= 3318.975 metres

so to get the speed,

S = Distance/Time

S = 3318.975/1119.803

S = 2.9638

S = 3m/s

which is option A
