Step 1
\[ 1 \text{ km/hr} = \frac{5}{18} \text{ m/s} \] So, \[ 60 \text{ km/hr} = 60 \times \frac{5}{18} \text{ m/s} = \frac{300}{18} \text{ m/s} = 16.67 \text{ m/s} \] Show more…

1. What is the speed of the train whose length is 210 metres? I. The train crosses another train (Howrah Express/12869) of 300 metres length running in the opposite direction in 10 seconds. II. The train crosses another train (Howrah Express/12869) running in the same direction at the speed of 60 km/hr in 30 seconds. - I alone sufficient while II alone not sufficient to answer - II alone sufficient while I alone not sufficient to answer - Either I or II alone sufficient to answer - Both I and II are not sufficient to answer - Both I and II are necessary to answer 2. What is the length of a running train crossing another 180 metre long train running in the opposite direction? I. The relative speed of the two trains was 150 kmph. II. The trains took 9 seconds to cross each other. - I alone sufficient while II alone not sufficient to answer - II alone sufficient while I alone not sufficient to answer - Either I or II alone sufficient to answer - Both I and II are not sufficient to answer - Both I and II are necessary to answer 3. What is the length of a running train? I. The train crosses a man in 9 seconds. II. The train crosses a 240 metre long platform in 24 seconds. - I alone sufficient while II alone not sufficient to answer - II alone sufficient while I alone not sufficient to answer - Either I or II alone sufficient to answer - Both I and II are not sufficient to answer - Both I and II are necessary to answer

A $120 \mathrm{~m}$ long train is moving in a direction with speed $20 \mathrm{~m} / \mathrm{s}$. A train $B$ moving with $30 \mathrm{~m} / \mathrm{s}$ in the opposite direction and $130 \mathrm{~m}$ long crosses the first train in a time? (a) $6 \mathrm{sec}$ (b) $36 \mathrm{sec}$ (c) $38 \mathrm{sec}$ (d) None of these

A train $A$ which is $120 \mathrm{~m}$ long is running with velocity $20 \mathrm{~m} / \mathrm{s}$ while train $B$ which is $130 \mathrm{~m}$ long is running in opposite direction with velocity $30 \mathrm{~m} / \mathrm{s}$. What is the time taken by train $B$ to cross the train A? (a) $5 \mathrm{~s}$ (b) $25 \mathrm{~s}$ (c) $10 \mathrm{~s}$ (d) $100 \mathrm{~s}$
