Solution: We are given the population mean $=42$

Now, in order to find which shift's mean is closest to population mean, we will find the mean of each shift.

The mean of shift 1 is:

$Mean=\frac{18+25+56+42+29+38+54+47+35+30}{10}=\frac{374}{10}=37.4$

The mean of shift 2 is:

$Mean=\frac{23+19+50+49+67+34+30+59+40+33
}{10}=\frac{404}{10}=40.4$

The mean of shift 3 is:

$Mean=\frac{19+22+24+40+45+29+33+29+39+59 }{10}=\frac{339}{10}=33.9$

The mean of shift 4 is:

$Mean=\frac{21+23+25+40+35+19+70+40+22+23 }{10}=\frac{318}{10}=31.8$

We clearly see the mean of shift 2 is close to the population mean. Hence the option B) Shift 2 is correct.

Use a system of equations:

For his trip on the way there:
D = 7*s

For his trip on the way home you have:
D = 5*(s+18)
