Question

in a 500 m race X runs 5 M per second. y is already 314 meters ahead of X when the race starts. if y beats X by 7 seconds then what is the speed of y?

Answer 1

speed of X = 5 m/s
time taken by X to complete the race = (500÷5) s = 100s
distance already covered by Y = 314 m
distance to be covered by Y to complete the race = (500-314) m = 186 m
Y beats X by = 7 s
time taken by Y to complete race = (100-7) s = 93 s
speed of Y = (186÷93) m/s = 2 m/s
