Mick and John were in a 100 meter race.
When Mick crossed the finish line, John was only at the 90 meter mark.
Mick suggested they run another race.
This time, Mick would start ten meters behind the starting line.
All other things being equal, will John win, lose, or will it be a tie in the second race?
Explain why?

1st race
Mick=100m,john=90m
2nd race
Mick=110m,john=x m
(100/110)=90/x
X=99 m
John will lose the race

Mick would still win the race.
Mick's speed is 100/90 times that of John
By the time John runs 100 metres, Mick would have run 111.1 metres (i.e., 100*100/90)
So, even if he started 10 metres behind the starting line, Mick would have crossed the finish line before John does.

John and his best friend Henry were going to take a test. On the night before the test, John studied all night, while Henry, on the other hand, didn't. Henry decided to just copy off of John's test. The next day, the teacher handed out the tests, and John immediately started to work. Henry carefully wrote down the same answers as John. Luckily for him, the teacher never noticed. A week later, the teacher handed the tests back to the class. John got every question right, and received an A. Henry got an F. If Henry correctly copied John's answers, and the teacher never noticed, why did he fail?
