Answer 2

Answer:

plz mark me as BRAINLIEST

hope this will help you.

Step-by-step explanation:

given :

given :speed = 25 km/hr = 25*(5/18) = 125/18 m/s

given :speed = 25 km/hr = 25*(5/18) = 125/18 m/sdistance travelled = 800 meter

given :speed = 25 km/hr = 25*(5/18) = 125/18 m/sdistance travelled = 800 meterto find : time taken

given :speed = 25 km/hr = 25*(5/18) = 125/18 m/sdistance travelled = 800 meterto find : time takensolution :

given :speed = 25 km/hr = 25*(5/18) = 125/18 m/sdistance travelled = 800 meterto find : time takensolution :as we know,

given :speed = 25 km/hr = 25*(5/18) = 125/18 m/sdistance travelled = 800 meterto find : time takensolution :as we know,speed = distance/time

given :speed = 25 km/hr = 25*(5/18) = 125/18 m/sdistance travelled = 800 meterto find : time takensolution :as we know,speed = distance/time125/18 = 800/time

given :speed = 25 km/hr = 25*(5/18) = 125/18 m/sdistance travelled = 800 meterto find : time takensolution :as we know,speed = distance/time125/18 = 800/timetime = 800*(18/125)

given :speed = 25 km/hr = 25*(5/18) = 125/18 m/sdistance travelled = 800 meterto find : time takensolution :as we know,speed = distance/time125/18 = 800/timetime = 800*(18/125)time = 115.2 seconds

given :speed = 25 km/hr = 25*(5/18) = 125/18 m/sdistance travelled = 800 meterto find : time takensolution :as we know,speed = distance/time125/18 = 800/timetime = 800*(18/125)time = 115.2 secondsso, Mohini will take 115.2 seconds to cover a distance of 800 meter at the speed of 125/18 m/s or 25 km/hr.
