Question

find the average speed of an object that Travels 400 kilometre in 2.5 hours​

Answer 1

$speed = \frac{distance}{time}$

$speed = \frac{400}{2.5}$

$speed = 160 \: kmph$

Hence,

$\boxed{\boxed{\pink{Speed-160kmph}}}$

Answer 2

average speed = total distace/total time

= 400/2.5

= 160 kmph
