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 |

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

@vino that speed 1200/(5/3) this term converted (1200*3)/5.

1 2/3 is a mixed-fraction so 1st we have to multiply denominator with which is in-front of fraction & add it to numerator then we will get a 5/3.

Distance = (240*5) = 1200km.
Speed = Distance/Time.
Speed = 1200/(5/3) km/hr.
= 1200*3/5.
= 720 km.
Speed = Distance/Time.
Speed = 1200/(5/3) km/hr.
= 1200*3/5.
= 720 km.

1(2/3) = 1.66.
5 hours/1.66hours *240 km/ph = 720 km/ph.
5 hours/1.66hours *240 km/ph = 720 km/ph.
