A jogger is running at a speed of 15 km/hr. In what time he will cross...
**Given Information:**
- Speed of the jogger = 15 km/hr
- Length of the track = 400 meters
**Approach:**
To find the time taken by the jogger to cross the track, we can use the formula:
\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]
**Calculation:**
1. Convert the speed from km/hr to m/sec:
- 15 km/hr = \(\frac{15 \times 1000}{60 \times 60}\) m/sec (1 km = 1000 m, 1 hr = 60 min = 3600 sec)
- 15 km/hr = \(\frac{15000}{3600}\) m/sec
- 15 km/hr ≈ 4.17 m/sec (approx.)
2. Substitute the values in the formula:
- Time = \(\frac{400}{4.17}\) sec
- Time ≈ 95.997 sec (approx.)
3. Round the value of time to the nearest whole number:
- Time ≈ 96 sec
Therefore, the jogger will cross the track in approximately 96 seconds.
**Answer:**
The correct option is (A) 96 sec.
