Question

a bus takes 30 min to cover a distance of 20 km/hr calculate its speed in km/hr and m/s​

Answer 1

Answer:

km/hr = 40 km/hr m/s = 144 m/s

Explanation:

Distance = 20 km

time = 30 mins --> 0.5 hours

Speed = Distance / time

speed = 20,000/ 0.5

Speed (in km/hr) = 40 km/ hr

speed in m/s = 40 km/hr * 18/5

therefore speed = 144 m/s

hope its correct

Answer 2

Answer:

time(t) = 30min. or 1800 sec

distance(dis.) = 18km or 18000 m

speed=18000/1800

speed = 10m/s
