Question

Calculate the speed of a bus if it travels 40km in 2 seconds. (be clear it is 2 secs. and not 2 hrs.)

Answer 1

Answer:

bro firstly change the unit to that unit which you wanted....i am doing this in m/s

40km = 40×1000 m (1km=1000 m)

=40000m

speed= distance/time

= 40000m/2s

= 20000m/s

Therefore ,20000m/s is your speed

Answer 2

Answer:

2×10⁴m/s

Explanation:

distance = 40 km or 4×10⁴m

and time = 2sec

so the speed will be 4×10⁴/2 m/s

=2×10⁴m/s
