Answer:
A.
Step-by-step explanation:
Let x = speed of the first car
the second car is 12 km slower so the seconds car speed is x-12
they each drove 2 hours so 1st car = 2x
2nd car = 2(x-12)
they drove 360 km
so you have 2x + 2(x-12) = 360
solve for x
2x+2(x-12) = 360
2x + 2x-24 = 360
4x-24 = 360
4x = 384
x = 384/4
x = 96
1st car drove at 96 km per hour
slower car drove at 96-12 = 84 km per hour
To convert from a percentage to a decimal, move the decimal twice to the left
11% = 0.11
200% = 2.00
20.07% = 0.2007
198.4% = 1.984
Hope this helps!
