Let speed of the car be c miles per hour.
Then speed of the train = (c + 48) miles per hour.
Changing the time taken by the car and train from minutes to hour.
20 =hrs. Time taken by the train = 20 minutes 60 36 3 hrs. 5 Time taken by the car 36 minutes 60
Forming the equation from the inform...
Since, distance travelled by the car and train is same. distance speed X time = speed of the car x time = speed of the train x time 3 cx(c48) x; -= 32 5c 240 9c 240 4c c 60 36 miles Therefore, distance= 60 x = n
