Answer 2

Answer:

The Rahim moves at a speed of $3.5km/hr.($Option $d)$

Step-by-step explanation:

Ram completed his journey $=5hours20minutes=5\frac{1}{3} hours=\frac{16}{3}hours.$

Rahim completed his journey $=6hours 45 minutes=6\frac{3}{4}= \frac{27}{4} hours.$

Ram journey : Rahim journey $=\sqrt{\frac{27}{4} /\frac{16}{3} }= \sqrt{\frac{27}{4} *\frac{3}{16} }=\frac{9}{8}$

Ram moves at a speed $=4km/hr$

                                      $=\frac{8}{9}*4=3.5km/hr.$
