Two cars get closer by $8$ m every second while travelling in opposite directions. They get closer by $0.8$ m every second while travelling in the same direction. The speeds of the two cars are:

Options:

Answer:

Solution:

$v_{1} + v_{2} = 8$ and $v_{1} - v_{2} = 0.8$ ; solving, $2 v_{1} = 8.8$ , so $v_{1} = 4.4$ m/s and $v_{2} = 8 - 4.4 = 3.6$ m/s. Option B.
