Question

An aeroplane takes 3 hours to cover a distance of 3,600 km. Another aeroplane
travels at a speed which is 100 km per hour less than the first aeroplane. How
long will the second aeroplane take to cover the same distance?​

Answer 1

Answer:

I will tell you the ans in 3 hr 16 min

3600/3=1200km/hr

1200-100=1100km/hr

T=3600/1100=3.27hr*60min=196.20 will come but we don't have to learn in point see we will only use 196 min ok = we will write in standard form =3hr 16 min.. very easy
