#1

A person travels along a straight road for the first half with a velocity ${ v }{ 1 }$ and the second half with velocity
${ v }
{ 2 }$. What is the mean velocity of the person?


#2

Time taken by person to travel first half
${ t }{ 1 }$ = (d/2) /
${v }
{ 1 }$
= d/${2v }{ 1 }$
Time taken by person to travel second half
${ t }
{ 2 }$ = d/2 / ${v }_{ 2 }$

d/ ${2v }_{ 2 }$
