Question

The Mackenzie River is 1183km longer than the St. Lawrence River. The sum of the two lengths is 7299km. How long is each river?

Answer 1

The St. Lawrence River is 3058km long and the Mackenzie River is 4241km long.

Step-by-step explanation:

Let's represent the length of the St. Lawrence River as x. Since the Mackenzie River is 1183km longer, its length can be represented as x + 1183. The sum of the two lengths is given as 7299km, so we can set up the equation:

x + (x + 1183) = 7299

Combining like terms and solving for x:

2x + 1183 = 7299

2x = 6116

x = 3058

Therefore, the St. Lawrence River is 3058km long and the Mackenzie River is 4241km long.
