1)

Solution:

Time taken by Rani to reach her school = 10 min.

And, Speed of the bicycle = 2 m/s

We know that,

$\: \: \: \: \: \: \: \: \: speed = \frac{distance}{time}$

$= > \: distance = speed \times time$

Therefore,

The distance between her home and her school

The distance between her home and her school = 10 x 2 m

The distance between her home and her school = 10 x 2 m = 20m

Answer

2)
