Answer:
Distance between them is 4,200 meters.
Explanation:
Consinder car A:
[tex]{ \bf{distance = speed \times time }}[/tex]
substitute:
[tex]distance = 20 \times (2 \times 60) \\ = 2400 \: m[/tex]
Consider car B:
[tex]distance = 15 \times (2 \times 60) \\ = 1800 \: m[/tex]
since these cars move in opposite directions, distance between them is their summation:
[tex]distance \: between = { \sum(distance \: of \: each \: car)} \\ = 2400 + 1800 \\ = 4200 \: m[/tex]
