Given :-
Speed (s) => 60km/hr = 60×5/18 = 300/18 m/s
Time (t) => 10min = 10×60 = 600s
To Find :-
Displacement[diameter] => ?
Solution :-
DISTANCE = SPEED × TIME
=> 300/18 × 600
=> 120000/18 m

2πr = 120000/18
2πr = 6666.66..
2×3.14r = 6666.66
6.28×r = 6666.66
r = 6666.66/6.28
r = 1061.57 m
Displacement = 2r = 2×1061.57 = 2123.14m ...ans...
