Hii,

Without wasting your time let's come to the question , it is asking us to find the speed of the bus.

Ok, so let's right down all the given details.

Distance- 15 Km.

Time duration- 2 hours.

As we can see that time is given in hours where as distance is given in Km, so, first of all convert both of them in equal standard forms.

15 km- 15*1000 meters= 15000m.

20 hours- 2*3600 seconds= 7200 seconds.

Distance- 15000 m and Time- 7200 seconds, respectively.

Now, applying the formula to calculate speed, i.e.

Speed= Distance travelled/Time taken

Speed= 15000/7200

Speed= 2.0 m/s or 2 m/s

And, please never forget to mention the unit after calculating the speed i.e. meter/second.

Thank you so much….
