Jane covered a distance of 340 miles between city A and city taking a total of 5 hours. If part of the distance was covered at 60 miles per hour speed and the balance at 80 miles per hour speed, how many hours did she travel at 60 miles per hour?

• ANS: 3 Hours
  
  X is the hours which Jane is travelled with 60 miles per hour. then 5-X is the hours which Jane travelled with 80 miles per hour. Total Distance becomes
  (X*60)+(5-X)*80 = 340. Solving this X will be 3 Hours
