Let the time taken by second car overtake to the first car be x hours after it started.
Total time taken by first car = (x + 1) hours.
Total distance covered by first car in (x + 1) hours = 60(x + 1) km .
Distance covered by second car in x hours = 80x .
Thus, Distance covered by first car is equal to second car .
∴ 60(x + 1) = 80x .
⇒ 60x + 60 = 80x .
⇒ 60 = 80x - 60x .
⇒ 60 = 20x .
{tex}⇒ \bf{\dfrac{60}{20}} = x{/tex}
∴ x = 3 .
Hence, the second car travelled in 3 hours to overtake the 1st car .
Therefore, time taken by second car to overtake the first car = 80x = 80 × 3 = 240 km.
