A) $2 \frac { 23 } { 28 } \text { miles per hour }$
B) $1 \frac { 23 } { 27 } \text { miles per hour }$
C) $1 \frac { 24 } { 28 } \text { miles per hour }$
D) $1 \frac { 23 } { 28 } \text { miles per hour }$

To find the average speed, divide the total distance by the total time: $\frac{5 \frac{2}{3}}{3 \frac{1}{9}} = \frac{17/3}{28/9} = \frac{17}{3} \times \frac{9}{28} = \frac{51}{28} = 1 \frac{23}{28}$ miles per hour.
