1.	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» Answer : 3.27 hours Step-by-step explanation : we know, $\boxed{\bf Speed=\frac{distance \ <klux>COVERED</klux>}{time \ taken}}$ An aeroplane takes 3 hours to cover a distance of 3,600 km Distance covered = 3600 km Time taken = 3 hours => Speed of first aeroplane = 3600 km/3 H = 1200 km/h Another aeroplane travels at a speed which is 100 km per hour less than the first aeroplane. => Speed of second aeroplane = (1200 - 100) km/h = 1100 km/h we have to find the time taken to cover the same distance by the second aeroplane. Distance covered = 3600 km 1100 km/h = 3600 km/time taken time taken = 3600/1100 time taken = 36/11 time taken = 3.27 hours (approximately) ∴ The time taken by the second aeroplane TAKE to cover the same distance = 3.27 hours

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»

3.27 hours

we know,

$\boxed{\bf Speed=\frac{distance \ <klux>COVERED</klux>}{time \ taken}}$

Distance covered = 3600 km

Time taken = 3 hours

=> Speed of first aeroplane = 3600 km/3 H

= 1200 km/h

Another aeroplane travels at a speed which is 100 km per hour less than the first aeroplane.

=> Speed of second aeroplane = (1200 - 100) km/h

= 1100 km/h

we have to find the time taken to cover the same distance by the second aeroplane.

Distance covered = 3600 km

1100 km/h = 3600 km/time taken

time taken = 3600/1100

time taken = 36/11

time taken = 3.27 hours (approximately)

∴ The time taken by the second aeroplane TAKE to cover the same distance = 3.27 hours
