Question

Vehicle running at a speed of 48 km per hour takes 6 hour to complete journey how much time will be taken to complete journey of its speed is 72 kilometre per hour

Answer 1

Answer:

Velocity = Distance /Time

In the first case you got 48km/hr for 6hrs if you use the above formula and solve for distance so that Distance =Velocity * Time and patch those numbers in the distance lets call it X ends up being 288km

Now on the second case where it goes with 72km/hr and the distance keeps beeing the same X=288km you can use the same formula again, this time in place of velocity you use 72km/hr and in place of distance you use 288km, this time solving for Time, its should looks something like Time=288/72=4 and since we never changed it from kms to meters or from hours to minutes or seconds even, The time it takes for it is 4hrs
