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

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.
