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: $4\dfrac{4}{9}\text{ feet per second}$

Step-by-step explanation:

Given: A frog jumps $\dfrac35$ feet in the span of $2\dfrac23$ seconds.

So, distance = $\dfrac35$ feet , time = $2\dfrac23$ seconds = $\dfrac83$ seconds.

Unit rate of movement = $\dfrac{\dfrac83}{\dfrac35}\text{ feet per second}$

$=\dfrac{40}{9}\text{ feet per second}\\\\=4\dfrac{4}{9}\text{ feet per second}$

Unit rate=    $4\dfrac{4}{9}\text{ feet per second}$
