Answer: The answer is (B) feet.
Step-by-step explanation: We are given the figure of a roller coaster and we are to select the most appropriate unit to measure the horizontal distance between the two ends of this loop.
Miles is not an appropriate unit to measure, because it will be 1 mile = 1609.34 metres and this will be too large and the loop will not be even 1 mile.
1 cm = 0.01 m, which is very small and so this is also not appropriate.
1 inch = 0.0254 metres, which is again very small.
Since 1 feet = 3.28 metres, so this will be the most appropriate unit to measure the horizontal distance between the two ends.
Thus, the correct answer is (B) feet.
