A car travels 120 km in 2 hours. After stopping for 30 minutes, it continues for 1 hour and covers another 80 km. What is the average speed for the entire journey?
Options:
A) 80 km/h
B) 90 km/h
C) 100 km/h
D) 110 km/h
Answer:
A) 80 km/h
Solution:
Total distance traveled = 120 km + 80 km = 200 km. Total time taken = 2 hours + 0.5 hours = 2.5 hours. Average speed = Distance / Time = 200 km / 2.5 hours = 80 km/h.
