Question

An aeroplane takes 3 hours to travel a distance of 3 300 km. Another aeroplane travels at a
speed which is 100 km per hour less than the first aeroplane. How long will it take to travel
the same distance by the second aeroplane?
​

Answer 1

Step-by-step explanation:

The solution comes likes this—

Speed of first aircraft = 3300/3 = 1100 km/h.

Now, the speed of the second aircraft is 100 km/h less than the speed of the first aircraft.

Therefore, speed of second aircraft = 1100–100 = 1000 km/h.

Therefore, time taken by the second aircraft to cover a distance of 3300 km will be—

Time = 3300 km/(1000 km/h) = 3.3 hours or 3 Hours and 18 Minutes.

Therefore, the second aircraft will take 18 minutes more than the first aircraft to cover the same distance.
