Question

Aaron travels 3 miles per hour in still water on his kayak. The expression 12 3 + x can be used to find the time it takes for him to travel with the current. If x represents the rate of the current, what does the denominator represent? A. the rate Aaron travels against the current B. the rate of the current C. the total distance Aaron kayaks D. the rate Aaron travels with the current

Answer 1

A. The rate Aaron travels with the current

Explanation:

Distance travelled = 3 mph in still water(downstream)

Time it takes for him to travel with the current = 12 / (3+x)

Where,

x = rate of the current

Denominator, 3 + x = The rate Aaron travels with the current

Therefore, the correct answer is

A. The rate Aaron travels with the current
