How many seconds will a 500m long train travelling from Sairang to Guwahati take to cross a man walking with a speed of 3km/hr in the direction of the moving train if the speed of train is 63km/hr?
A)
15 sec
B)
30 sec
C)
45 sec
D)
10 sec
Step-by-step solution:
1. **Identify the given values:**
- Length of the train (Distance to be covered) = 500 m
- Speed of the train ($V_t$) = 63 km/hr
- Speed of the man ($V_m$) = 3 km/hr
- Direction: Both are moving in the same direction.
2. **Calculate Relative Speed:**
When two objects move in the same direction, the relative speed is the difference between their speeds.
Relative Speed = $V_t - V_m = 63 ext{ km/hr} - 3 ext{ km/hr} = 60 ext{ km/hr}$.
3. **Convert Relative Speed to meters per second (m/s):**
To convert km/hr to m/s, multiply by $5/18$.
Relative Speed = $60 imes (5/18) = 300/18 = 50/3 ext{ m/s}$ (approximately 16.67 m/s).
4. **Calculate Time taken to cross:**
The formula for time is $\text{Time} = \text{Distance} / \text{Speed}$.
$\text{Time} = 500 / (50/3)$
$\text{Time} = 500 imes (3/50)$
$\text{Time} = 10 imes 3 = 30 ext{ seconds}$.
Therefore, the train will take 30 seconds to cross the man. Option (b) is correct.
