Question

An aeroplane covers a certain distance at a speed of 240 kmph in 5 hours. To cover the same distance in 1hours, it must travel at a speed of: ( A ) 300 kmph ( B ) 360 kmph ( C ) 600 kmph ( D ) 720 kmph

Answer 1

Answer:

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
