Question

An aeroplane covers a certain distance at a speed of 240 km per hour in 5 hours To cover the same distance in 1 2/3 hours, it must travel at a speed of:​

Answer 1

Answer:

720 kph

Step-by-step explanation:

Distance = (speed × time)

∴ Distance = (240 × 5) = 1200 km

Speed = Distance/Time

$∴ \: speed \: = \frac{1200}{1 \frac{2}{3} }$

$∴ \: speed \: = \frac{1200}{ \frac{5}{3} }$

$∴ \: speed \: = \frac{1200 \times 3}{5}$

$∴ \: speed \: =( 240 \times 3) = 720 \: kph$

∴ New speed = 720 kph (ANS)

Hope this helps you :)

Answer 2

Step-by-step explanation:

speed = distance / time

distance=240×5=1200 km

speed =1200/5/3 km /hour

1200 ×3/5

=240×3

=720 km/hour
