The ratio of boys to girls in a group is 5:3. If there are 24 more boys than girls, work out how many girls there are

5x = 3x + 24

2x = 24

x = 12 so the # of girls = 12 * 3 = 36

Let they meet after second car travels for x hours'
let v be the speed of second car and V be speed of first car.
Then time taken by first car=x+2
V(x+2)=vx (distance covered is same.)
$\frac{v}{V} = \frac{x+2}{x} 
subtract 1 from both sides
 \frac{v-V}{V} = \frac{2}{x} 
v-V= \frac{2V}{x}$
