Question

Alex covers 50 m from centre O to point A on the boundary of the stadium. What is the minimum distance (in m) that Shalini​ should cover to reach A?​

• A. 50
• B. 70
• C. 90
• D. 100

Answer 1

The correct option is D 100

Point O is the centre of the stadium.
So, Radius OA = 50 m
To reach point A covering the minimum distance, Shalini has to move from B to O and then from O to A.
Shalini covers = BO + OA = 50 m + 50 m = 100 m
