Pierre is rowing his kayak on a lake he moves 1 1/4 miles in 18 minutes at this rate how far would he move in 30 minutes
A. 18 miles
B. 2 1/12 miles
C. 5/72 miles
D. 30 5/72 miles
To find out how far Pierre would move in 30 minutes, we can set up a proportion:
1 1/4 miles / 18 minutes = x miles / 30 minutes
To solve for x, we can cross multiply and divide:
(1 1/4) * 30 = 18 * x
(5/4) * 30 = 18 * x
150/4 = 18x
150/4 ÷ 18 = x
37.5/4 ÷ 18 = x
37.5/72 = x
Therefore, Pierre would move 37.5/72 miles in 30 minutes.
The answer is C. 5/72 miles.
