Question

a boat has a top speed of 30 knots and a displacement of approximately 80,000 tons. express the top speed in miles per hour and the displacement in metric tonnes (1 knot = 1 nautical mile per hour; 1 metric tonne = 1000 kilograms). click here to view the uscs measurements. click here to view the uscs to metric conversions. the boat has a top speed of approximately 34.5 mile(s) per hour (round to the nearest tenth as needed.) the boat has a displacement of approximately 72575 metric tonne(s) (round to the nearest whole number as needed.)

Explanation:

Step1: Convert knots to miles per hour

1 knot = 1.15078 miles per hour. Given top - speed is 30 knots. So, speed in miles per hour = 30×1.15078 = 34.5234 miles per hour. Rounding to the nearest tenth, we get 34.5 miles per hour.

Step2: Convert tons to metric tonnes

1 ton = 0.907185 metric tonnes. Given displacement is 80000 tons. So, displacement in metric tonnes = 80000×0.907185 = 72574.8 metric tonnes. Rounding to the nearest whole number, we get 72575 metric tonnes.

Answer:

The boat has a top speed of approximately 34.5 miles per hour.
The boat has a displacement of approximately 72575 metric tonnes.
