Mark me as BRAINLIEST too.

Step-by-step explanation:

given :

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

distance travelled = 800 meter

to find : time taken

solution :

as we know,

speed = distance/time

125/18 = 800/time

time = 800*(18/125)

time = 115.2 seconds

so, 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.
