The coordinate grid below represents a town. curtis house is at(-4,-6).and jeans house is at(-4,3).
each unit on the grid represents 1 mile. if curtis can ride his bike at a constant rate of 12 miles per hour, how many minutes would it take curtis to ride from his house to jeans house. plz show your work(if u are able to for this problem)

Okay, first you need to know the distance...since the x coordinate does not change we can see that the distance between the two points is just y2-y1, in this case:

3--6=9 so the houses are 9 miles apart.

distance=velocity times time...

d=vt so we can say

t=d/v, we found d=9 and we are told that v=12mph so

t=9mi(h/12mi)

t=0.75 hr, but the question want the time in minutes so

0.75hr(60min/hr)=45 min

So it takes Curtis 45 minute to reach his friends house 9 miles away riding at 12 miles per hour.
