Answer 1

Answer: Izzy's speed is
`6(9)/(10)` mph.

Step-by-step explanation: You have to divide the number of miles by the number of hours.

`4(3)/(5) / (2)/(3)\\`

Convert the mixed fraction
`4(3)/(5)` to an improper fraction.

`(4 * 5 + 3)/(5) / (2)/(3) = (23)/(5) / (2)/(3)`

Multiply the first fraction by the reciprocal of the second fraction (the second fraction upside down).

`(23)/(5) / (2)/(3) = (23)/(5) * (3)/(2) = (23 * 3)/(5*2) = (69)/(10)`

Convert the result into a mixed fraction.

69 / 10 = 6 with a remainder of 9

A:
`6(9)/(10)`
