Marks: +1, -0

A car travels

105 {\km}

in

3 {h}

and a train travels

252 {\km}

in

4 {\h}

. The ratio of speed of the car to that of the train is

$2: 7$
$3: 5$
$9: 11$
$5: 9$

Solution:

We know that, Speed

={{ \Distance }}/{ { \Time }}

∴ Speed of car

={105}/{3}=35 {\km} \/ {\h}

∴ Speed of train

={252}/{4}=63 {\km} \/ {\h}

Required ratio

=35: 63=5: 9
