Question 95406
Steve traveled 600 miles at a certain speed. Had he gone 20mph faster, the trip would have taken 1 hour less. Find the speed of his vehicle. 
:
Let s = the "certain speed"
:
The faster speed = (s+20)
:
Write a time equation: Time = Dist/speed
:
The problems states;
Certain speed time - Faster speed time = 1 hr
{{{600/s}}} - {{{600/((s+20))}}} = 1
:
Is this set up enough for you?
