Question

last week, your delivery runs took 7 hours 12 minutes on monday, 6 hours 46 minutes on wednesday, and 6 hours 53 minutes on friday. what was your average time for a delivery run? 6 hours 46 minutes 6 hours 53 minutes 6 hours 57 minutes 6 hours 59 minutes 7 hours 10 minutes

Explanation:

Step1: Convert time to minutes

Monday: \(7\times60 + 12=432\) minutes.
Wednesday: \(6\times60+46 = 406\) minutes.
Friday: \(6\times60 + 53=413\) minutes.

Step2: Calculate total time

Total minutes \(=432 + 406+413=1251\) minutes.

Step3: Calculate average time

Number of days \(n = 3\). Average minutes \(\frac{1251}{3}=417\) minutes.

Step4: Convert back to hours and minutes

\(417\div60 = 6\) hours and \(57\) minutes (\(417=6\times60 + 57\)).

Answer:

6 hours 57 minutes
