If a person swim 120 meter in a minute . What is his speed on km/h and m/s. How much time will he take to swim a distance of 45 meter. With the speed mentioned above find the distance in 50 second

Dear Student

time = 1 min = 60 sec = 1/60 hr
distance  = 120 m = 0.12 km
speed = distance /time = 0.12/(1/60) = 7.2 km/h = 2 m/s

time = ?
distance  = 45 m
speed = 2 m/s 
time = distance /speed = 45/2 = 22.5 s

time = 50 s 
speed = 2 m/s 
distance = ?

distance = speed × time = 2 × 50 = 100 m

Regards
