Question : 80 of 100

Marks: +1, -0

A can run 22.5 m at a certain time period while B runs 25 m at that time period. In a kilometre race, B beats A by how much distance?

100 m
$111 1/9$ m
25 m
50 m

Solution:

For a

25 {m}

race,

{B}

defeats

{A}

by

25-22.5=2.5 {m}

So, for

1 {m}

race,

{B}

defeats

{A}

by

\;{2.5}/{25}=\;{1}/{10} {m}

Therefore, for

1 {km}(1000 {m})

race,

B

will defeat

A

by

\;{1000}/{10}=100 {m}
