1. You have that:
-The <span>police car accelerates 60 meters per second.
- The minivan has a speed of 45 meters per second and is 600 meters ahead of the police car at the beginning of the chase.
2. Therefore, you have:
V1xt=V2xt-600
V1 is the speed of the minivan and V2 is the speed of the police car
3. The time is:
t=-600/V1-V2
t=-600/(45-60)
t=40 seconds</span>
1.25 times 15 will get you how much she has used, and then subtract that from 35.4 to get the amount left in the bottle
2x+29=10x-27
29=8x-27
56=8x
x=7
2(7)+29=43
10(7)-27=43
360-43(2)=274
274/2=137
measure of V = 137
