Kane’s speed was 6.86 m/s.
Did you manage to solve it within 1 minute? Tom took 14 2/7 secs to finish the race, thus Kane would have taken the same time to run 98m when Tom crossed the finishing line.
Using the Distance-Speed-Time triangle, we can use the Distance divided by the Time to get Kane’s speed, hence, 6.86 m/s.
