Answer:
60 km
455 km
23 km
60 km
82.5 km
Step-by-step explanation:
Time = t
Speed = s
Distance is given by
t = 2 hours
s = 30 km/h
Distance driven is 60 km.
t = 7 hours
s = 65 km/h
Distance driven is 455 km
t = 
s = 46 km/h
Distance driven is 23 km
t = 45 minutes = 
s = 80 km/h
Distance driven is 60 km
t = 
s = 55 km/h
The distance driven is 82.5 km
