Talk about question 15 in this case we are given that the distance between two train stations or distance between the two train stations is given as 20 kilometers and if a train moves with a constant speed of 60 kilometer per hour but is a time taken by the train to reach the next station so it can be deduced by saying that this is the initial point and this is the final point let's say this is this station one and this is the station two and the distance between these two stations is already given as 20 kilometers.
00:33
And the speed with which it is traveling, let's call it v, that's given as 60 kilometers per hour.
00:44
We need to find a time which it takes to.
00:47
So clearly, we know that the formula for the time would be the distance or the speed.
00:53
And the distance is already given as 20.
00:54
And we have to make sure that the units would be same.
00:57
So yes, it is given us kilometer over here.
00:59
And the speed is also given.
01:00
And kilometer per hour.
01:02
So we can right away divide distance with velocity and we have to make sure that since the velocity is in kilometer per hour.
01:11
So the answer, the unit of the answer which we'll get from this will be in hours.
01:18
The time would be one over three hours, but in the options, only one option is an hour and the rest are in minutes and seconds...
