Ineed on number 8b the answer is 5 minutes but i don’t know how they got that

Time taken for 3 laps is 1/4 hour which is equal to 15 minutes

(1/4x60 minutes=15 minutes)

(1 hour =60 minutes)

Time taken for 1 lap=15 minutes/3 laps

=5 minutes

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

it could be 1,3 and more others to create a cylinder.
