Salma takes 15 minutes from her house to reach her school on a bicycle. If the bicycle has a speed of 2 m/s, calculate the distance between her house and the school.
Given:
Salma takes 15 minutes from her house to reach her school on a bicycle.
To do:
To calculate the distance between her house and the school if the bicycle has a speed of 2 m/s.
Solution:
Time taken $t=15\ minutes=15\times60\ seconds=900\ seconds$
Speed $=2\ m/s$
So, the distance between her house and school $=speed\times time$
$=2\times900$
$=1800\ m$
$=1.8\ km$ [Because $1\ km=1000\ m$]
So, the distance between Salma's house and school is $1800\ m$ to $1.8\ km$.
