Show answer & explanation
Correct answer: D
Solution: Use the formula time = distance ÷ speed.
Substitute the values: time = 345 ÷ 50.
Calculate the division: 345 ÷ 50 = 6.9 hours.
Convert 0.9 hours to minutes: 0.9 × 60 = 54 minutes, so the journey takes 6 hours 54 minutes.
Final answer: 6.9 hours (6 hours 54 minutes).
