Here’s a practice question from Dr. Romano (DAT Destroyer):

Choose A if Column A is larger
Choose B if Column B is larger
Choose C if the columns are equivalent
Choose D if the answer cannot be determined

It takes a boat 6 hours to travel 120 miles along a current that has a speed of 4 mph.

A) The time it would take the boat to travel 100 miles in still water
B) The time it would take the boat to travel 60 miles against the current

---

Solution:
Speed with current = 120 ÷ 6 = 20 mph
Speed in still water = 20 − 4 = 16 mph
Speed against current = 16 − 4 = 12 mph


Column A → 100 ÷ 16 = 6.25 hr = 6 h 20 min
Column B → 60 ÷ 12 = 5 hr


✅ Answer: A — Column A is larger.


6 hours 20 minutes is greater than 5 hours, so the correct choice is A.
