Answer 1

HELLO.....FRIEND!!

THE ANSWER IS HERE,

Let the distance be d.

Speed of 1st student=> 3.75km/h.

Speed of 2nd student=> 3km/h.


From the question,


$= > \: \frac{d}{3.75} + \frac{1}{2} = \frac{d}{3}$

$= > \: \frac{d}{3} - \frac{d}{3.75 } = \frac{1}{2}$

$= > \: d( \frac{1.25 - 1}{3.75} ) = \frac{1}{2}$

$= > \: d( \frac{0.25}{3.75} ) = \frac{1}{2}$

$= > \: \frac{d}{15} = \frac{1}{2}$


$= > \: d = \frac{15}{2}$

=> d = 7.5 km.
