Group Title
Wilma drove at an average speed of 60mph from her home in City A to visit her sister in City B.
She stayed in City B 25 hours, and on the trip back averaged 40mph. She returned home 42hours after leaving.
We have to determine how many miles x is it from City A to City B.
1. In terms of x, express Wilma's driving time from A to B
It is ____________
2. In terms of x, her return driving time is ______________
3. Her TOTAL driving time is: _____________ (trip time minus visiting time)
So answer from 1. PLUS 2. set equal to 3. is the equation:
_______________________ = ___________________.

#1 avg speed=60mph; distance=x, then time=x/60 #2 time=x/40 #3 total driving time=4225 x can be obtained by solving: x/60+x/40=4225

so to solve X, (x/60) + (x/40) = 17 I would have to multiply 60 by each side, correct? and solve?

better multiply both sides with 120... its a multiple of both 40 & 60...

17*120 = 2040.. right? then does that make the x/60 + x/40 = to x? since it all cancels out?

after multiplying with 120: 2x+3x=17*120 5x=17*120 x=17*120/5

you don't need to find 17*120 outrightly... 120/5=24

\[120*\left( x/60+x/40 \right)=(120*x/60)+(120*x/40)=2x+3x\]
