Answer:

Total distance around the track is 176m.

Speed of the body = total distance covered/total time taken

= 176/4

=44metres/min

Find the distance covered in 6 minutes:

if 1 min= 44m

then 6 min=(44X6)/1 =264

There the distance covered around the track from starting point = 264-176

=88 metres

This corresponds to distance around half the track, which means displacement corresponds to 180 degrees

Hence, the displacement distance is the diameter.

total distance around the track= 176m

Circumference=Xdiameter.....176=22/7 XD

D=176X7/22

=56 (therefore the displacement is 56meters)
