Study Notes
Problem Description
- Ajay walks at 4 km/hr.
- He doubles his speed after walking halfway.
- He walks for a total of 12 hours.
- Find the total distance travelled.
Speed and Time Calculation
- Let the total distance be 'd' km.
- Half the distance is 'd/2' km.
- Time taken to walk 'd/2' km at 4 km/hr is (d/2) / 4 = d/8 hours.
- Time taken to walk the remaining 'd/2' km at 8 km/hr is (d/2) / 8 = d/16 hours.
- Total time taken is d/8 + d/16 = 3d/16 hours.
- Given total time is 12 hours. So, 3d/16 = 12.
Solving for Distance
- Solving for 'd': 3d = 12 * 16
- d = 192 / 3 = 64 km
Answer
- The total distance travelled is 64 km.
