Question

Mohit came out of his home and walked 200 m towards East to reach Post Office. From Post Office, he took a rickshaw to reach market 500 m away. From market, he took a short-cut and walked 300 m to reach home. What distance did he travel?

• A. $1km$
• B. $0m$
• C. $200m$
• D. $400m$

Answer 1

Answer: (A)

$1km$

Distance is calculated as the sum of lengths of the paths travelled irrespective of direction of motion.
$distanc{e}_1$ = distance between home and Post Office = $200m$
$distanc{e}_2$ = distance between Post Office and market = $500m$
$distanc{e}_3$ = distance between market and home = $300m$
Hence $totaldistancetravelled=distanc{e}_1+distanc{e}_2+distanc{e}_3=200m+500m+300m=1000m=1km$.
