Question

While driving in an exotic foreign land, you see a speed limit sign that reads 180,000 furlongs per fortnight. How many miles per hour is this? (One furlong is 1/8 mile, and a fortnight is 14 days. A furlong originally referred to the length of a plowed furrow.)

Answer 1

Answer:

66.96

Step-by-step explanation:

Furlong = 1/8 mile

Fortnight = 14 days

Day = 24 hours

If the speed limit is 180,000 furlongs per fortnight, converting the units from furlongs per fortnight to miles per hour:

$V=180000\frac{furlong}{fortnight}*\frac{1\ mile}{8\ furlong}*\frac{1\ fortnight}{14\ days}*\frac{1\ day}{24\ hours} \\V=66.96\ mph$

The speed limit on this exotic land in 66.96 miles per hour.
