Answer:
i. time = distance/speed
= 40/120
= 1/3 hours
ii. distance = speed × time
= 120 × 3
= 360 km
iii. average speed = total distance/ total time
= 250/2.5
= 100 km/h
for the last question, the time is 2.5 hours because 6.00 to 8.30 is 2 hours 30 minutes. so the 30 minutes you must change to hour and plus with 2. thus, u will get 2.5 hours
