Question

If the speed of a car is 20m/s .How long does it take to cover a distance of 1km?​

Answer 1

Answer: 50 seconds

Explanation:

1km=1000m

Distance/speed=time

1000/20=50

50 seconds

Answer 2

Explanation:

Hey, there!!

Here,

speed (s)= 20m/s

distance (d)= 1km

= 1000m

now,

we have formula,

$t = \frac{d}{s}$

putting value,

$t = \frac{1000m}{20m/ s }$

cancelling the like terms,

$t = 50s$

Therefore, the time is 50s.

Hope it helps...
