Question ✍️✍️:-
If a car travels 120km in 165 hours - How much time it would take to over 560 km at the same speed ?
Answer ✍️✍️:-
3 hours and 45 minutes.
Speed = distance/time, so speed = 120/3 = 40kmh.
At 40kmh, it takes 4 hours to cover 160km and 3 hours to cover 120km. That means that it takes 15 minutes to cover 10km (because 15 is a qaurter of 60 and 10 is a quarter of 40).
Take 10km from 160 and you get 150, so to get the time to cover 150km you must subtract 15 minutes from 4 hours, leaving you with 3 hours and 45 minutes.
