Answer: 22 hours 28 minutes

Step-by-step explanation: 0843 means 8:43am and 0711 means 7:11am military time. In that order there is 22 hours 28 minutes from 8:43am today to 7:11 am tomorrow. The question itself is rather confusing so if this is not what you meant please let me know and I will re-do it.

The driving distance from Chicago to San Francisco is 2,142 miles. The Hathaway family left Chicago on Monday morning, December

Answer:

They arrive on Monday, December 13th

Step-by-step explanation:

First, we know that this family must drive a total of 2,142 miles.

They average 50 miles per hour and drive 6 hours each day, thus we can see that they drive (50)(6)=300 miles per day.

Now, to know how many days it will take them to drive the total of 2,142 miles we are going to divide the total amount of miles between the number of miles driven per day:

2,142÷300= 7.14

Thus, it takes them 7.14 days to drive 2,142 miles.

If we round this (since the number is greater than 7 this would mean it takes them more than 7 days and they would stop at 7 for the day) to the next digit, we would have that it will take them 8 days to get to San Francisco.

Thus, since they start on December 6th (day 1), December 7th would be day 2 and following this pattern we would have that the eighth day would be December 13th.

Now, since the days repeat every 7 days and we now that December 6th was monday, we would have that the day they arrive to San Francisco (December 13th) is monday too.

Answer:

a) m =589.734kg

b) n = 8 people (rounded down)

Step-by-step explanation:

The first step is to calculate the maximum load after safety considerations ( $T_{max}$

Since we know that the maximum tension the cables can withstand is 19500N (or 19.5kN). To calculate ( $T_{max}$ we multiply this value by $\frac{2}{3}$ (as per the given safety consideration.
