A train travels 180 km in 3 h. Find its speed in: (i) km/h (ii) m/s (iii) What distance will it travel in 4 h if it maintains the same speed throughout the journey?
(i)
Find its speed in km/h
Answer
Speed = 60 km/h
(ii)
Find its speed in m/s
Answer
Speed = 16.67 m/s (approximately)
(iii)
Answer
Distance = 240 km
Explanation
(i) Using the formula Speed = Distance/Time = 180 km / 3 h = 60 km/h (ii) Converting 60 km/h to m/s: 60 × (5/18) = 16.67 m/s (iii) Using Distance = Speed × Time = 60 km/h × 4 h = 240 km
