1. A train passes city X at 8.25 am and city Y at 11.05 am. The distance between city X and Y is 320 miles. What is the average speed in miles per hour of the train?
- A. 135
- B. 135
- C. 135
- D. 135
Answer: Option B
Explanation:
Here, 8:25 am to 11:05 am = 2 hr 40 min = 160 min = 160/60 hr = 8/3 hr
Speed = distance / time = 320 / (8/3) = 120 mph
