Question 821771: it takes 2 hours to complete a journey at a speed of 45kmpr hour .find the time taken by the train to complete journey at a speed of 60km per hour Answer by LinnW(1048) (Show Source):
You can put this solution on YOUR website! First find the distance traveled.
( 2 hours )( 45 km/hour ) = 90 miles
Use distance = rate x time to see how long it takes
to travel 90 miles at 60 km/hour .
90 = time x 60
divide each side by 60
90/60 = time
3/2 = time in hours
