Explanation Formula used: Speed= distance time Calculation: Consider the speed of the canoe to cover 6 miles be x . Also, the canoe covers an additional 3 miles at 1 miles per hour faster than that of the constant speed. Total time taken for the entire journey by the canoe is 4 hours. Now, By the definition of speed, it is observed that, time= distance speed Therefore, the equation formed by the data provided is, 4 = 6 x + 3 x + 1 4 = 6 ( x + 1 ) + 3 x x ( x + 1 ) 4 = 6 x + 6 + 3 x x ( x + 1 ) 4 = 6 x + 6 + 3 x x 2 + x 4 x 2 + 4 x

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.
