Answer: <em>60 meters</em>
Step-by-step explanation:
<em>if the car travels 20 meters in 15 seconds</em>
<em>you want to take 45 and divide it by 15, giving you 3</em>
<em>now you want to multiply 20x3</em>
<em>which will get you </em><em>60 meters</em>
Lets just say the number is equal to x.
-1(2x+3)=2*(-4x-3)
Distribute on both sides
-2x-3=-8x-6
Add 3 to both sides
-2x=-8x-6
Add 8x to boths sides
6x=-6
Divide Both Sides by -1
x=-1
The numbers is -1.
45 seconds the difference from 7 45 to 8 is 15 plus another 30 to get 8:30 which is a 45 second difference
