please help can not figure equation 8 grade math student
I have the same question in my book but I do not know how to solve it.
Anwer :62km/per hour and 74km/per hour
Is their any smart people out there
The one car travel 18 miles more than the other.
The speed of one car is 12 mph faster than the other. To get 18 miles ahead of the other car, they must have been driving for 1 1/2 hours.
One car went 93 miles in an hour and a half:
93 / (3/2) = 93 * 2/3 = 62 mph
The other car went 111 miles:
111 / (3/2) = 111 * 2/3 = 74 mph.
I just realized that all my units should have been km rather than miles. Same numbers, different units.
