Hello, I need help with this problem. I can figure out the answer, but I cannot figure out how to set up the problem and solve. The question reads as this...
If the speed were increased by 10mph, a 420 mile trip would take 1 hour less time. How long will the trip take at the slower speed?
So far, I have
D=RT
420=x()
420=x+10()
What goes in the time part?
Please help
