Question 765938: a speeding boat travelled a distance of x km at a constant speed of 80km/h. an ocean liner travelled the same distance at 60 km/h. if the difference in time taken was 2 hours, calculate x. Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! a speeding boat travelled a distance of x km at a constant speed
of 80km/h.
an ocean liner travelled the same distance at 60 km/h.
if the difference in time taken was 2 hours, calculate x.
:
Write a time equation; time = dist/speed
:
liner time - boat time = 2 hrs - = 2
multiply equation by 240, resulting in
4x - 3x = 480
x = 480 km is the distance
:
:
Check this by finding the time of each
480/60 = 8 hrs
480/80 = 6 hrs, a diff of 2 hrs
