Frank can mow lawns at a constant rate of 6/5 lawns per hour. How many lawns can he mow in 50 hours

Answers

Final answer:

Frank can mow at a rate of 6/5 lawns per hour. In 50 hours, by multiplying the rate by the total time, we find that Frank can mow a total of 60 lawns.

Explanation:

To calculate this, we should utilize basic mathematical operations that apply to rate problems. We know Frank's rate is 6/5 lawns per hour, and we are given a total time of 50 hours.

So, to find the total number of lawns Frank can mow in 50 hours, we simply multiply his rate (6/5) by the total time (50 hours). This gives us (6/5) * 50 = 60 lawns.

Therefore, Frank can mow 60 lawns in 50 hours if he maintains his constant rate.

well, we know his rate is 6/5 lawns/hour that means he can do 6 lawns in 1 hour, well, how many can he do in 50 hours?

$\bf \begin{array}{ccll} lawns&hours\n \cline{1-2} 6&5\n x&50 \end{array}\implies \cfrac{6}{x}=\cfrac{5}{50}\implies \cfrac{6}{x}=\cfrac{1}{10}\implies 60 = x$
