Question

While driving in an exotic foreign land, you see a speed limit sign on a highway that reads 180,000 furlongs per fortnight. How many miles per hour is this?

a) 5 mph
b) 10 mph
c) 15 mph
d) 20 mph

Answer 1

To convert 180,000 furlongs per fortnight to miles per hour, we can use conversion factors to convert between the units. The speed limit is approximately 67 mph.

To convert 180,000 furlongs per fortnight to miles per hour, we need to use conversion factors to convert between the two units. First, let's convert furlongs to miles. There are 8 furlongs in a mile, so:

180,000 furlongs × (1 mile / 8 furlongs) = 22,500 miles

Next, let's convert fortnights to hours. There are 14 days in a fortnight and 24 hours in a day, so:

1 fortnight × (14 days / 1 fortnight) × (24 hours / 1 day) = 336 hours

Now, we can calculate the speed in miles per hour by dividing the distance by the time:

22,500 miles / 336 hours = 66.964 miles per hour

Rounded to the nearest whole number, the speed limit is approximately 67 mph.
