 Hi, and welcome to the session. Today we will discuss the following question. The question says, a loaded truck travels 14 kilometers in 25 minutes. If the speed remains the same, how far can it travel in five hours? Let's proceed with its solution. First of all, let us make a table to represent distance traveled in kilometers and time taken in minutes. In question, it is given that the truck travels 14 kilometers in 25 minutes. So the distance traveled is 14 kilometers, and the time taken is 25 minutes. Now, if the speed remains the same, how far can it travel in five hours? That means we are given the time taken, that is five hours, which we need to convert into minutes. Now, we know that in one hour, there are 60 minutes. So in five hours, there are 60 into five minutes. That is equal to 300 minutes. So the time taken is 300 minutes. And let us assume that the distance traveled is 8 kilometers. Now, recall that the two quantities, X and Y, are said to be in direct proportion if an increase or decrease in X is followed by an increase or decrease in Y in such a manner that the ratio X upon Y remains constant and positive. And in case of direct proportion, we use the relationship X1 upon Y1 is equal to X2 upon Y2, where Y1 and Y2 are the values of Y corresponding to the values X1 and X2 of X, respectively. Here, X is distance traveled by the truck and Y is the time taken by the truck. Now, speed remaining same, more will be the distance traveled by the truck, then more will be the time taken. So that means it is a case of direct proportion. So we have the relationship X1 upon Y1 is equal to X2 upon Y2. So here, in this case, X1 is equal to 14 and X2 is equal to 8. Also, Y1 is equal to 25 and Y2 is equal to 300. Now, substituting these values in this relationship, we get 14 upon 25 is equal to A upon 300. On cross-multiplying, this gives A into 25 is equal to 14 into 300. This implies A is equal to 14 into 300 upon 25, which is equal to 168. Therefore, distance traveled by the truck in five hours is equal to 168 kilometers. Therefore, 168 kilometers is a required answer. With this, we've finished this session. Hope you must have enjoyed it. Goodbye and take care.
