Question

A furlong is a distance of 220 yards. A fortnight is a time period of two weeks. A race horse is running at a speed of 5.00 yards per second. What is his speed in furlongs per fortnight?

Answer 1

Speed of race horse is `27490.91` furlongs per fortnight.

Explanation:

There are `14` days in a fortnight and hence `14xx24=336` hours

i.e. `336xx60=20160` minutes or `20160xx60=1209600` seconds

As the race horse runs at a speed of `5.00` yards per second,

heruns `5xx1209600=6048000` yards in a fotnight.

There are `220` yards in a furlong,

Therefore `6048000` yards is equivalent to

`6048000/220=27490.91` furlongs (rounded to `2dp`)

Hence, speed of race horse is `27490.91` furlongs per fortnight.
