Question

If the Distance is 142 km and time is 2hours what is the speed ?​

Answer 1

Step-by-step explanation:

speed is equal to distance divided by time. Therefore speed is 142/2 which is equal to 71 km/h.

Answer 2

Answer:

We know

speed=distance/time

here

speed=142/2

speed=71 km/h

if convert it into m/s

then it's

$71 \times \frac{5}{18} = \frac{355}{18} \\ = 19.722$

therefore the speed of body in it's SI unit

is 19.72m/s

or in it's km/h, it's 71km/h
