A and B start at the same time for the same place from the same point with speeds of 50 km/hr and 60 km/hr respectively. If in covering the journey, A takes 4 hours longer than B, the total distance of the journey is

• A. 600 km
• B. 2400 km
• C. 1000 km
• D. 1200 km

Answer 1

Answer:

D. 1200 km

Let the distance be ‘x’ km x/50 – x/60 = 4 ⇒ (6x – 5x)/300 = 4 ⇒ 6x – 5x = 1200 ⇒ x = 1200 km
