An object has traveled 20 meters in 40 seconds what is its average speed
Mice21 [21]

Hello,


To solve we need to know the formula for speed

The formula is D/T=S     (Distance of time=speed)

Now all we have to do is plug in the numbers.

20/40= 1/2 or 0.5

SO the speed is 0.5 m/s


Have a great day!
