Question

Ryan needs to travel from the lighthouse to the boat dock to go on a dolphin cruise, but he only has

enough gas in his jeep to drive 30 miles. He grabs a map of the island, which shows that the distance
from the lighthouse to the boat dock is 4 inches. The map shows the scale for every half an inch on the
map is really 3 miles on the island. Use proportions to solve for the distance Ryan will need to travel on
the island. Does he have enough gas?
Island Map:
I
4 in
1/2 inch = 3 miles

Answer 1

Answer: 24 miles. Yes

Explanation:

1/2in = 3 miles so 1in = 6 miles

6 x 4 = 24 so he will need 24 miles worth of gas to make it.

Answer 2

2.25 miles no Ryan does not have enough gas.

Explanation:

first draw your proportion

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

Next fill it out

30 miles 2.25 miles

=

4 inches 3 miles

Then multiply 30 miles by 3 miles and you get 90

After you mutliply 30 by 3 which is 90, divide 90 by 4 and you get 2.25 miles.

Ryan only has enough gas in his jeeep to drive 30 miles he needs to travel 2.25 miles to get to the island, so he does not have enough gas to get to the island.
