Solution :-
1) A) Speed .
2)
→ Distance = Speed * Time .
3)
→ Speed = Distance ÷ Time .
4)
→ Unit of Speed = kilometer/hour .
5)
→ Litre is not a unit of distance .
6)
→ Distance covered = 50 km
→ Time = 4 hours
So,
→ Speed = Distance / Time = 50/4 = 12.5 km/hr
7)
→ Distance covered = 2 km
→ Speed = 4 km/h
So,
→ Time = Distance / Speed = 2/4 = (1/2) hours .
8)
→ Average speed = 18 km/h
→ Time = 5 hours
So,
→ Distance covered = 18 * 5 = 90 km .
9)
→ Average speed = 45 km/h
→ Time = 4.5 hours
So,
→ Distance covered = 45 * 4.5 = 202.5 km .
10)
→ Usual speed in opposite direction = 55 + 60 = 115 km/h
→ Distance covered = 345 km .
So,
→ Time taken = Distance / Usual speed = 345/115 = 3 hours .
