Answer:
The answer is <u>A. 990.</u>
Step-by-step explanation:
Now, to find the greatest possible length of time any of the mowers operates.
The 3 lawn-service mowers operate at the average length of time = 930 minutes.
So, the total length of time the 3 lawn mowers take =
The least length a mowers operates = 900 minutes.
Now, to find the greatest possible length of time any of the mowers operates:
Let be the greatest possible length of time any of the mowers operates.
<em>As, any one of the mowers operates greatest length.</em>
<em>So, rest of the two mowers be least at length.</em>
According to question:
<em>Subtracting both sides by 1800 we get:</em>
<u><em>Thus, the greatest possible length of time any of the mowers operates is 990 minutes.</em></u>
Therefore, the answer is A. 990.
