Answer:He has to travel 300 km in 6 hours.
He traveled 100 kms in an hour.
2 hours got wasted in check point due to coronavirus.
He has 3 hours to cover remaining 200kms
Speed = distance/time
= 200km/3hrs
= 66.6km/h
His average speed of entire journey is.
He traveled a total of 4hrs.
1 hour speed is 100km/h
2,3,4 hour speed is 66.6km/h
Avg speed = ( 100 + 66.6 + 66.6 + 66.6 )/4
= 74.95 km/h
