Question: Solve this problem please!.!?
Two people left a bus terminal at the same time and oppisite direction!. Person A was in heavy traffic and had to travel 20mi/h slower than person B After 3 hours they were 270 miles apart!. How fast was each bus going!?Www@Enter-QA@Com
Answers:
We will use math:
Va is the speed of person A!.
Vb is the speed of person B!.
We have:
Va = Vb - 20
distance D = 270
The formula is:
D = Va*3 + Vb*3
To solve:
270 = (Vb - 20)*3 + (Vb*3)
270 = 3Vb - 60 + 3Vb
330 = 6Vb
Vb = 330/6
We get:
Vb (Speed of Person B) = 55 mi/h
and Va (Speed of Person A) = 35 mi/hWww@Enter-QA@Com

If you want to calculate the speed!. Then you have to do distance divided by time!.Www@Enter-QA@Com
