Answer 2

Do your own home work

Here's some hint:

The difference between 90 and 72 km/h is only 18 km/h.  And the bike travel exactly 10 second at 72 km/h first.  So how far does a motorcycle travel in 10 seconds (at 72 mk/h).

So the question is how long does it take to go that distance at 18 km/h.

Go do your homework.

Good luck...
