A 300 m long train crosses a platform which is five times of its length, in 7 minutes 40 sec. What is the speed of the train?
1
\(2 \frac{19}{23} \mathrm{~m} / \mathrm{s}\)
2
\(1 \frac{17}{23} \mathrm{~m} / \mathrm{s} \)
3
\( 3 \frac{21}{23} \mathrm{~m} / \mathrm{s} \)
4
\( 2 \frac{17}{23} \mathrm{~m} / \mathrm{s}\)
