Question

Tracy ran 100 m when she started the clocks ahead 10 seconds when she finished the clocks said 15 seconds... what is the answer​

Answer 1

I'm assuming you mean to say that the clock already showed 10 seconds when she started the race.

It took her 5 seconds to run 100 meters since 15-10 = 5.

To find her speed, divide 100 over 5 to get 100/5 = 20 meters per second

20 meters per second is approximately equal to 44.7387258 miles per hour.

Something seems really off because the fastest record speed for a human runner was around 28 mph. Though of course, this is just a hypothetical math problem.
