You can put this solution on YOUR website! If it takes 3.5 hours to travel a certain distance at 100km/hr, how long would it take to travel the same distance at 130km/hr?
**
travel time is inversely proportional to speed
(100/130)*3.5≈2.69 hrs
..
alternate method:
travel time=distance/speed
distance=travel time at 100 km/hr=100*3.5=350
travel time at 130 km/hr=350/130≈2.69 hrs
