Question

A frog jumps ( 3/5 feet in the span of 2 2/3 seconds. Find the unit rate, in feet per second, that the frog is moving at. Express any improper fractions as mixed numbers.

Answer 1

Answer:
`4(4)/(9)\text{ feet per second}`

Explanation:

Given: A frog jumps
`\frac35` feet in the span of
`2\frac23` seconds.

So, distance =
`\frac35` feet , time =
`2\frac23` seconds =
`\frac83` seconds.

Unit rate of movement =
`(\frac83)/(\frac35)\text{ feet per second}`

`=(40)/(9)\text{ feet per second}\\\\=4(4)/(9)\text{ feet per second}`

Unit rate=
`4(4)/(9)\text{ feet per second}`
