If a train travels 180 km/h at a speed of 60 km/h, how much less time will it take to complete the same journey at a speed of 70 km/h:

by

A) 20 mins
B) 23 mins
C) 26 mins
D) 29 mins

🧠 Explanation (Math):

Given: Distance = 180 km; time at 60 vs 70 km/h; find time saved
Step 1: t₁ = 180/60 = 3 h
Step 2: t₂ = 180/70 ≈ 2.5714 h = 2 h 34 min 17 s
Step 3: Difference ≈ 25 min 43 s ≈ 26 minutes
Final Answer: 26 mins
