An aeroplane covers a certain distance at a speed of 240 kmph in 5 hours. To cover the same distance in 1
hours, it must travel at a speed of:
hours, it must travel at a speed of:Answer: Option
Explanation:
Distance = (240 x 5) = 1200 km.
Speed = Distance/Time
Speed = 1200/(5/3) km/hr. [We can write 1 hours as 5/3 hours]
 Required speed = |
 |
1200 x | 3 |  km/hr |
= 720 km/hr. |
| 5 |

Time decrease by 3times. 5/3=1*2/3.
Therefore speed increases by 3 times=3x240=720km/hr.
Therefore speed increases by 3 times=3x240=720km/hr.

Those who says Answer as 720 please read the question. Its given that speed for a time of 1Hr should be foun out, not for 1+ (2/3) hrs.

Even if the aeroplane travels in the speed of 720km/hr it can the distance of 1152km..... As the nearest answer is 720km/hr.

Speed: 240Km/Hr
Time: 5Hrs
Distance= Speed*Time
D= 240*5
=1200m
Given, Time=5/3Hr
Speed= Distance/Time
= 1200/(5/3)
= 1200*3/5
=720 Km/Hr
Time: 5Hrs
Distance= Speed*Time
D= 240*5
=1200m
Given, Time=5/3Hr
Speed= Distance/Time
= 1200/(5/3)
= 1200*3/5
=720 Km/Hr

Those who says answer as 720, why you are taken time as 5/3 hr instead of 1 hr as given in d example.

Those who says the answer is 720kmph please concentrate on my statement----.
If the answer is 720kmph then it means if we multi 720kmph with the given time of 1hr then we get the this which is 1200km isn't.
But did we get it?!

Here the speed is given in Km/hr and time in hours, why the hours are not converted into mins ?

240 Km/hr in 5 hours
5X60=300min
in 1 2/3 hrs to travel the same distance
1 2/3X60=100
=240/100X300=720
5X60=300min
in 1 2/3 hrs to travel the same distance
1 2/3X60=100
=240/100X300=720

There are 3 speeds 12m, 14m and 16m covering equal distance. What is the average speed? please solve it.
