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 $1.8\ km$.
