Question

Maria can peel at least $10$ dozen bananas per hour and at most $15$ dozen guavas per hour. Calculate the possible amount of time maria will take to peel $60$ dozen guavas.

• A. $4\le r\le 6$
• B. $5\le r\le 7$
• C. $6\le r\le 8$
• D. $7\le r\le 9$

Answer 1

The correct option is A $4\le r\le 6$

Given that Maria peels at least $10$ dozen bananas per hour and $15$ dozen guavas per hour.

Then, it takes her to peel $60$ dozen guavas $=$ $\frac{60}{15}=4$ hours

And $60$ dozen bananas $=$ $\frac{60}{10}=6$ hours

Then, the possible amount of time Maria will take to peel $60$ dozen guavas $=$ $4\le r\le 6$
