Problema Solution
A car covers a distance of 2592 km.The number of hours taken for the journey is one half the number representing the speed in km per hour.Find the time taken to cover the distance.
Answer provided by our tutors
Let the time taken be x.
Then the speed is 2x.
Speed = Distance/Time
Or, 2x =2592/x
Or, 2x^2 = 2592
Or, x^2 = 2592/2 = 1296
x = sqrt(1296) = 36
Time taken = 36 hours
Speed = 2*36 = 72 km/h
