Answer 2

given that
speed of the bicycle = 2m/s
time taken by Salma to reach school from her house = 15minutes = 15 x 60s= 900s
we know that
speed = distance / time
Hence
distance = speed x time
= 2m/s x 900 sec
= 1800m
= 1.8m
distance between Salma house and school = 1.8m

hope this will help you
