On Sunday, a strong gale blows near Beth’s house. The best estimate for the wind speed is miles/hour. Note: One knot is about the same as 1.15 miles/hour.

2 Answer

  • The answer is: The best estimate for the wind speed is 47.15 - 54.05 miles/hour.

    The knot is a unit of speed equal to one nautical mile per hour, approximately 1.15 mph.

    The ISO standard symbol for the knot is kn.

    v(wind) = 41-47 kn; speed of strong gale.

    v(wind) = 41 · 1.15 mph.

    v(wind) = 47.15 mph.

    v(wind) = 47 · 1.15 mph.

    v(wind) = 54.05 mph.

  • Answer:

    The correct answer is 47.15 - 54.05.

    I got this right on a test. I hope this helps!
