Question

A small turtle moves at a speed of 647 furlongs per fortnight. Find the speed of the turtle in centimeters per second. Note that 1 furlong = 220 yards and 1 fortnight 14 days

Answer 1

Answer: 10.760 cm/s

Explanation:

We have the following velocity expressed in furlongs per fortnight:

$647\frac{furlongs}{fortnight} \frac{220yards}{1 furlong} \frac{1 fortnight}{14 days}=10167.14 \frac{yards}{day}$

Now we have to convert this to cm/s, knowing $1day=24h$, $1h=3600 s$ and $1yard=91.44 cm$

$10167.14 \frac{yards}{day} \frac{1 day}{24 h} \frac{1h}{3600 s} \frac{91.44 cm}{1 yard}=10.760 \frac{cm}{s}$

Therefore, the velocity of the turtle in cm/s is 10.760 cm/s
