9. You kayak 7 miles in 34 hours. How many
miles do you kayak per hour?

Divide miles paddled by time.

7 / 3/4

When dividing by a fraction flip the fraction over and multiply:

7 x 4/3 = (7 x 4) /3 = 28/3 = 9 and 1/3 miles per hour

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

can you put the picture up?
