What is the ratio of the mans running speed to the sidewalk

Reference no: EM13562807

A suspicious-looking manruns as fast as he can along a moving sidewalk from one end to theother, taking 3.50 s. Then security agentsappear and the man runs as fast as he can back along the sidewalk to his starting point, taking 11.0 s. What is the ratio of the man's running speed to the sidewalk's speed? (running speed / sidewalk speed)
