Question

A furlong is 220 yd. A fortnight is 2 weeks. Convert a speed of one furlong per fortnight to millimeters per second.

a) 0.02 mm/s
b) 0.2 mm/s
c) 2 mm/s
d) 20 mm/s

Answer 1

To convert a speed of one furlong per fortnight to millimeters per second, perform multiple unit conversions: furlongs to yards, yards to millimeters, and fortnights to seconds. The conversion is approximately 1666.4 millimeters per second.

Step-by-step explanation:

To convert a speed of one furlong per fortnight to millimeters per second, we need to perform a series of unit conversions. First, we need to convert furlongs to yards by multiplying by 220. Then, we convert yards to millimeters by multiplying by 0.9144. Finally, we convert fortnights to seconds by multiplying by 1,209,600. Combining all these conversions, we get:

1 furlong/fortnight = (1 furlong) * (220 yards/furlong) * (0.9144 millimeters/yard) * (1,209,600 seconds/fortnight)

Simplifying this expression, we find that 1 furlong/fortnight is equal to approximately 1666.4 millimeters per second.
