Question

How far would a car travel in 4 seconds if it is moving with a speed 45 km /h ?

Answer 1

Dear Student!

Use the formula

Dist. = Speed x time

Distance = 12.5* x 4

Thus distance travelled =500m i.e 0.5km

*= Divide speed with 3.6 to convert it from km/hr to m/sec

Answer 2

Answer:

distance=?

time=4seconds

=4/60×60

time=1/900hours

speed=45km/h

Distance=time×speed

=1/900×45

so45 ×20=900

so 1/20km

1/20×1000

50m it is answer
