A car takes 6 hours to cover a distance of 540 Km. how much should the speed in kmph be maintained to cover the same direction in 3/2th of the previous time?
60 Kmph
62 kmph
75 kmph
77 kmph
Answers
Answer:
before,
distance=540km
time=6h
speed = 540/6=90kmph
now,
distance=540km
time=6×2/3=9hours
speed=540/9=60kmph
hence option A 60kmph is the right answer
Answer:
A) 60 kmph is the correct response.
Step-by-step explanation:
We can use the following algorithm to determine the necessary speed:
Distance x Duration Movement
Assuming that it will take 6 hours and 540 km to travel the distance, Thus, it is possible to determine the vehicle's starting pace as follows:
Pace = 540 km per six hours, or 90 kmph.
We must now calculate the pace necessary to travel the same distance in 3/2 the time (i.e., 6 * 3/2 = 9 hours).
The method can be used to determine the necessary speed: Speed = 540 km / 9 hours = 60 kmph
Therefore, choice A) 60 kmph is the correct response.
To conclude up:
≈ 540 km of distance to be travelled
Initial processing time: 6 hours
Initial speed = Distance / Time = 540 km / 6 hours = 90 kmph
Time taken to cover the distance in 3/2th of the previous time = 9 hours
Required speed = Distance / Time = 540 km / 9 hours = 60 kmph
