Question 863965: After driving for five hours at a certain speed, Dominic realizes that her could have covered the same distance in three hours if he had driven 20mph faster. What is his current speed? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! let the current speed be x
distance = 5x
speed increase (x+20)
time = 3
3(x+20) is the distance
equate distance
5x=3(x+20)
5x=3x+60
2x=60
x=30 current speed
