Answer:
A.
1. Distance = Speed x Time
= 262.5km
2. Speed = Distance / Time
= 200m x 20 sec
= 400m/sec
3. Time = Distance / Speed
= 390km / 60 km/h
= 6 hours
4. Speed = Distance / Time
= 473km / 5.5h
= 86 km/h
5. Distance = Speed x Time
= 9.3m/s x 86sec
= 799.8m
B.
1. Speed = Distance / Time
= 600km / 5h
= 120 km/h
2. Speed = Distance / Time
= 24km / 3hrs
= 8km/h
3. Speed = Distance/Time
= 2400km/6hrs
= 400km/h
