A trucker drove for 4 hours before he encountered icy road conditions. He reduced his speed by 20 MPH and continued driving for 3 more hours. find his average speed during the first part of the trip if the entire trip was 325 miles. Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! speed = x initially
distance = 4x
..
then speed = x-20
distance = 3(x-20)
...
4x+3(x-20)=325
4x+3x-60=325
7x=385
/7
x=55 mph initially
