Question

A car completes a journey in 6hr with a speed of 50kmph. At what speed must it travel to complete the journey in 5hr.

Answer 1

Given ,

Speed , s = 50 km/hr

Time Taken , t = 6 hrs.

So , Total Distance , d = s*t = 50 km/h * 6 h = 300 km .

New Time , t¹ = 5 hrs.

So , New Speed = d/t¹ = 300 km / 5 hr = 60 km/h .....
