Question

Two people are running from the same place at speed of $3km/hr$ and $2km/hr$. Find the distance between them after $10minutes$ if they move in the same direction

• A. $333.3m$$
• B. $166.67m$
• C. $427m$
• D. None of these

Answer 1

Answer: (B)

$166.67m$

Relative speed of two people in same direction$=(3-2)$km/hr=$1$km/hr

Time$=10$minutes$=10\times 60$s$=600$s

$\therefore$ Distance covered=Relative speed $\times$ Time

$=1$km/hr $\times 600$s$=1\times \frac{5}{18}$m/s$\times 600$s

$=166.67$m
