Question

Answer 1

Amy’s speed is 200/38=5.26 m/s approx. Richard takes 8 seconds longer than Amy, so his speed is 200/46=4.35 m/s approx. Lucy is 6 seconds behind Richard so her speed is 200/52=3.85 m/s approx. (Rob is 3 seconds behind Lucy so his speed is 200/55=3.64 m/s approx.)

This table shows the finishing order:

NAME    SPEED TIME

Amy           5.26    38

Richard     4.35    46

Lucy          3.85    52 

Rob            3.64    55

Lucy took 52 seconds to run 200m. The other info here was not asked for but I believe it helps to complete the picture.
