Answer: Izzy's speed is [tex]6\frac{9}{10}[/tex] mph.
Step-by-step explanation: You have to divide the number of miles by the number of hours.
[tex]4\frac{3}{5} / \frac{2}{3}\\[/tex]
Convert the mixed fraction [tex]4\frac{3}{5}[/tex] to an improper fraction.
[tex]\frac{4 * 5 + 3}{5} / \frac{2}{3} = \frac{23}{5} / \frac{2}{3}[/tex]
Multiply the first fraction by the reciprocal of the second fraction (the second fraction upside down).
[tex]\frac{23}{5} / \frac{2}{3} = \frac{23}{5} * \frac{3}{2} = \frac{23 * 3}{5*2} = \frac{69}{10}[/tex]
Convert the result into a mixed fraction.
69 / 10 = 6 with a remainder of 9
A: [tex]6\frac{9}{10}[/tex]
