Answer:

I believe 88 buoys

Step-by-step explanation:

The race is 25 miles long and theirs a buoy every 500 yards

There are 44000 yards in 25 miles

44000 (yards) divided by 500 (yards) is 88 (buoys).

500 yards      44000 yards

--------------- =  --------------------

1 buoy              x buoys

Going diagonally, 1 × 44000 is 44000.

44000 ÷ 500 = x

x = 88

il63 [147K]

Answer:

The unit rate is \frac{27}{20}\text{ page/minute}

Step-by-step explanation:

Given : Kenny reads \frac{4}{9} page in \frac{3}{5} min.

To find : What is Kenny's unit rate?

Solution :

Kenny reads \frac{4}{9} page in \frac{3}{5} minute

This can be written as,

\frac{4}{9}\text{ page}=\frac{3}{5}\text{ minute}

Divide both side by \frac{9}{4}

\frac{4}{9}\times \frac{9}{4}\text{ page}=\frac{3}{5}\times \frac{9}{4}\text{ minute}

1\text{ page}=\frac{27}{20}\text{ minute}

The unit rate is \frac{27}{20}\text{ page/minute}
