Answer 2

Hello Dear!!!

Here's your answer...

A bus runs at a speed of 54km per hour.

One hour=60 mins

1 minute=60 seconds

60 mins = 60×60

60 mins = 3600seconds.

One hour= 3600 seconds.

Let,the distance travelled in 20 secs be x

Km-----time
54-----3600
x-------20

Cross multiplication..

54×20 = 3600*x

1080=3600x

1080/3600=x

0.3 = x

So...The bus travels 0.3 km in 20 seconds.
