Answer» Correct Answer - Option 2 : 12 km/h Given: Total distance = 60 km Formula used: Speed = Distance/Time Time = Distance/Speed Calculation: (1/5)th of the distance = 12 km 12 km travels in 1 hour Remaining distance = 60 - 12 ⇒ 48 km So, 48 km covers in 4 hours (i.e. 5 -1) hour ∴ Speed = 48/4 = 12 km/h |
