Marks: +1, -0

In covering a certain distance, the speeds of A and B are in the ratio 3:4. If A arrives at the destination 20 minutes later than B. the time (in hours) taken by A to arrive at the destination is

$2{1/3}$
$2{1/2}$
$1{1/3}$
$1{1/4}$

Validate

Solution:

[because

\Tµ=1/\speed

for same distance]
1 unit = 20 minutes

=1/3

hours
∴ Time taken by A = 4 units

=4/3=1{1/3}

hour
