$\frac{3}{10} s e c o n d$
$\frac{1}{200} s e c o n d$
$\frac{11}{41} s e c o n d$

Answer 1

Correct answer: 18 seconds

Explanation: ✅ Correct Answer: A. 18 seconds 📚 Explanation: Since they are moving in the same direction, the relative speed is (41 - 11) = 30 kmph. In meters per second, this is 30 multiplied by (5/18), which equals 25/3 m/s. Time taken is distance divided by speed: 150 divided by (25/3) = (150 multiplied by 3) divided by 25 = 6 multiplied by 3 = '18 seconds'. This formula calculates the time required to close the gap.
