How long would it take for a ball moving in a straight line to travel 246 meters?
1) It takes the ball 2 seconds to make 1 rotation.
2) The ball makes 7 rotations per meter.
The OA is C.
This is my solution,
Statement 1, 2 seconds per rotation, but no info on how many rotations per meter.
Statement 2, rotation per meter but no info on how long per rotation.
1 & 2 together works. Hence, the correct answer is C.
Has anyone another strategic approach to solve this DS question? Regards!
