1. The problem statement, all variables and given/known data

15. Convert the following times. All units must be shown as well as cancellations.

f) 0.35 minutes to years.

19. a) The maximum speed reached by a standing skate boarder is about 14.7 m/s. Would the skate boarder get a ticket in a 30 km/h speed zone?

b) A snail crawls 100 times slower than a normal human walk (3km/h). How many times slower than the skate boarder is the snail?

2. Relevant equations

3. The attempt at a solution

You did not really state where your stuck...which it makes it a bit hard to help you.

But here is a try for the first q

"Convert the following times. All units must be shown as well as cancellations.

f) 0.35 minutes to years"

This is a dimensional analysis type q. Used commonly in chemistry and higher classes physics.

for example, 50 mL to L

50mL x 1L/1000mL

as you can see we converted over a unit we want and cancelled the units we do not want. Your question follows a similar path...just keep converting until you get to years ex. mins to hours to days to months to finally years.

The other questions follow a similar method.
