Answer:

0.7°

Step-by-step explanation:

From the figure:

CF = 4000.2 miles, CE = 4000.01 miles

so FT = √CF² - CT², TE = √CE² - CT²

so FT = 40 miles, TE = 8.94 miles

so ½ × 4000.2 × 4000.01

xsin angle FCE = ½ × 4000 × 140 + 8.94

so sin angle FCE = 0.0122

so angle FCE = 0.7°

so m SB = 0.7°

$\text {Laura = } 12 \text { years } 3 \text { months }$

$\text {Lisa = } 11 \text { years } 7 \text { months }$

$\text {Deborah = } 11 \dfrac{1}{2} \text { years } = 11 \text { years } 6 \text { months }$

$\text {Elizabeth = } 11 \dfrac{1}{3} \text { years } = 11 \text { years } 4 \text { months }$

-----------------------------------------------------
Find Total :
-----------------------------------------------------
$\text {Total = } 12 \text { yr } 3 \text { mth } + 11 \text { yr } 7 \text { mth } + 11 \text { yr} 6 \text { mth} +11 \text { yr } 4 \text { mth}$

$\text {Total = } 45 \text { years } 20 \text { months }$

-----------------------------------------------------
Find Average :
-----------------------------------------------------
$\text {Average = } (45 \text { years } 20 \text { months }) \div 4$

$\text {Average = } 560 \text { months } \div 4$

$\text {Average = } 140 \text { months } \div 4$

$\text {Average = } 11 \text { years } 8 \text { months }$
