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:



a. 300 kmph



b. 360 kmph



c. 600 kmph



d. 720 kmph

Answer 1

$hello \: mate$
first knw formula
distance=speed*time
speed=distance/time
time=speed/distance

now read the question.they given aeroplance covers distance of 240 km/hr in 5 hours so we need the total distance of 5 hours...

distance=speed*time so distance=240*5=1200km

now we have to speed cover in 1+2/3 hours=5/3 hours

speed=distance/time speed=(1200/5/3)kmph=(1200*3/5)kmph=
720 kmph

hope this helps uu...!!
