Question

A boat can travel 77 9/16 nautical miles in 8 1/2 at how many knots is the boat traveling ​

Answer 1

Divide miles by time:

77 9/16 miles / 8 1/2 hours =

Rewrite as I’m proper fractions:

1241/16 / 17/2

Flip the second fraction over and multiply:

1241/16 x 2/17 = (1241x2)/(16x17) =

2482/272 = 9 1/8 miles per hour

Answer 2

Hi there!

Simplify each terms:

$77\frac{9}{16}*8\frac{1}{2}=77\frac{9}{16}*8\frac{8}{16}$

Divide each terms:

$77\frac{9}{16}*8\frac{8}{16}=9\frac{2}{16}$

Simplify terms:

$9\frac{2}{16}=9\frac{1}{8}$

Final Result:

$9\frac{1}{8}$
