Answer:
→ from 8AM to 9 AM amit covered distance = 30 km.
→ from 8AM to 10 AM amit covered distance = 60 km.
→ from 8AM to 11 AM amit covered distance = 60 km.
→ from 8AM to 12 AM amit covered distance = 120 km.
as we can see that, distance is increasing 30 km in every hour . we can conclude that, Amit runs the auto with uniform speed .
Solution ii) :-
→ Time spend by amit outside the house daily is = 10:30PM - 6AM = 22 : 30 - 6 : 00 = 16 : 30 = 16 hours 30 minutes.
Solution iii) :-
→ Uniform speed of Amit = 30 km/h
→ Distance covered by Amit in 1(1/2) hours = Speed * Time = 30 * (3/2) = 45 km.
Solution iv) :-
→ Uniform speed of Amit = 30 km/h
→ Time taken to cover 15 km = Distance / Speed = 15 / 30 = (1/2) hours = 30 minutes.
