A car is moving with the speed of 120 km/h in 4 hours. What should be the speed of car if the car covers the same distance in 3 hours and 20 minutes?

  • (A) 142 km/h
  • (B) 140 km/h
  • (C) 124 km/h
  • (D) 144 km/h
  • Solution: Now, let’s solve this problem step by step.
  • Step 1: Find the Distance
  • Speed = 120 km/h
  • Time = 4 hours
  • Distance = Speed × Time = 120 km/h × 4 hours = 480 km
  • Step 2: Find 3 hours 20 minutes in hours
  • 3 hours 20 minutes = 3 + 20/60 = 3 + 0.3333 = 3.3333 hours
  • Step 3: Find the Required Speed
  • Speed = Distance/Time = 480 km/3.3333 hours = 144 km/h
  • Therefore, the answer is 144 km/h, i.e., Option D.
