Explanation Given: A company is looking into establishing an excursion ferry connection between two tourist locations 40 miles apart on a river bank. The speed of the river current is 2 mph, and the company would like to limit the round trip to at most 4.5 hours. Assuming that the power of the ferry is constant and result in the speed in still water being v. Calculation: We have been given that the speed of the current is 2mph and the speed of the speed of ferry in still water is v. The speed of the ferry going upstream = v − 2 The speed of the ferry going downstream = v + 2 Hence, using the relation of distance, time and velocity, we have Speed = Distance Time ⇒ Time = Distance Speed Time taken by ferry in going upstream is given by t 1 = 40 v − 2 Similarly, time taken by ferry in going downstream is given by t 2 = 40 v + 2 Therefore, the total time taken in the round trip is given by t = t 1 + t 2 t = 40 v + 2 + 40 v − 2 Now, it has been given that the company would like to limit the round trip to at most 4

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experime…
