Question

An aeroplane is flying at a speed of 720 km/hr ,how far will it fly in 15 seconds.​

Answer 1

Answer:

3000m

Step-by-step explanation:

we want to make 720km/h into m/sec

for that multiply 720 with 5/18

720×5/18=200 m/sec

200×15=3000m

so the aeroplane will travel 3000 m i.e,3 km

Answer 2

Answer:

$Hello$ $mate!$

First we have to convert 720 km/h to m/s ,as the time is given in seconds.

$so,$ $\frac{720km}{1 hr}$  × $\frac{1000m}{3600secs}$

    $= \frac{720000}{3600}$   $= 200 m/s$

Therefore, speed of the aeroplane is 200 m/s.

speed = $\frac{distance}{time}$

  $200$  $= \frac{distance}{15}$

  $distance = 200$ × $15$

                = $3,000 m$

hence, the distance  aeroplane  flew =  3,000 m   (or)

                                                              = $3 km$.
