A) 5 m
B) 10 m
C) 20 m
D) 23 m
Correct Answer: A
Solution :
The movements of A are as shown in Figure (O to P, P to Q, Q to R, R to S and S to T). Since TS = OP + QR, so T lies in line with O. \[\therefore \] A's distance from the starting point O \[=OT=(RS-PQ)\] \[=(15-10)m\] \[=5\,m.\]You need to login to perform this action.
