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

#### Explanation:

There are $14$ days in a fortnight and hence $14 \times 24 = 336$ hours

i.e. $336 \times 60 = 20160$ minutes or $20160 \times 60 = 1209600$ seconds

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

heruns $5 \times 1209600 = 6048000$ yards in a fotnight.

There are $220$ yards in a furlong,

Therefore $6048000$ yards is equivalent to

$\frac{6048000}{220} = 27490.91$ furlongs (rounded to $2 \mathrm{dp}$)

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