Question

The speed of three car are in ratio 2:3:4 then ratio between the time taken by these car to travel the same distence is....?

Answer 1

$<b>Hi there!$

$<b>Let the speed of three cars be 2x,3x and 4x respectively.Let the distance be a km.$

$<b>Time taken=distance /speed$
$<b>Time taken by,------------- First car=2x/a Second car=3x/a Third car=4x/a$
$<b>So ratio between the time taken will be-$
$<b>2x/a:3x/a:4x/a$
They all have x/a common, so dividing by x/a gives us:
$<b>2:3:4$

●$<b>Hence the ratio between the time taken by these cars is 2:3:4.$
