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- 20 minutes.
As we can see that time is given in minutes 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 minutes- 20*60 seconds= 1200 seconds.
Distance- 15000 m and Time- 1200 seconds, respectively.
Now, applying the formula to calculate speed, i.e.
Speed= Distance travelled/Time taken
Speed= 15000/1200
Speed= 12.5 m/s
And, please never forget to mention the unit after calculating the speed i.e. meter/second.
Thank you so much….
