Since , t=3 h
v=55 km/h
therefore, d= 55×3
=165 km
Then, v if covers 2.2 h will be= 1650/22
=75 km/h
v=55 km/h
therefore, d= 55×3
=165 km
Then, v if covers 2.2 h will be= 1650/22
=75 km/h

Answer:
Distance = 3km
Time = 2.2hrs
= 22/10 hrs
=11/5 hrs
speed = distance/time
=3×5/11
=15/11 km/h
=1.45 km/h
