Here in the Slokha the words Yojana and Nimesha are the units of Distance and Time of Ancient times

The Yojana=9 miles and Nimesha=0.21333 Seconds

Underlined text is number 2202

2202 X 9 = 19818

1 nimesha = 0.21333 seconds

1/2 nimesha = 0.10665 seconds

Speed=Distance / Time =19818/0.10665=185822 miles/second=299044 km/s
