Question

tell fast please​

Answer 1

Answer:

As we all know speed =distance/ time. so we just have to put the values in this formula and you will get your answer, but the basic thing you have to take care about the unit of the quantity

speed always comes in km per hour… meter per sec.

so before you solving this you have to take care of the unit.

in the above question here, distance -200 meter and time - 24 sec

so the speed will be 25/3 meter per sec.

Answer 2

$\huge\mathcal\blue{Answer}$

$\pink{Given}\pink{\longrightarrow}$

Distance travelled=200m

Time taken=40 seconds

$\red{Formula used}\red{\longrightarrow}$

$average \: speed = \frac{total \: distance \: travelled}{total \: time \: taken}$

$\orange{Solution}\orange{\longrightarrow}$

$average \: speed = \frac{200}{40}$

$average \: speed = 5m {s}^{ - 1}$
