Amit starts from a point A and walks to another point B and then retur...
Understanding the Problem
Amit has two modes of transportation: walking and driving. The total time taken when he walks to point B and returns by car is 6 hours and 45 minutes. If he had driven both ways, it would have taken 2 hours less.
Converting Time
- Total time walking to B and returning by car: 6 hours 45 minutes = 6.75 hours
- If driving both ways took 2 hours less:
- Time driving both ways = 6.75 hours - 2 hours = 4.75 hours
Setting Up the Equation
Let:
- T_w = time taken to walk from A to B (in hours)
- T_d = time taken to drive from A to B (in hours)
From the problem, we have the following relationships:
1. T_w + T_d = 6.75 (A to B walking and return driving)
2. 2 * T_d = 4.75 (Driving both ways)
From the second equation, we find T_d:
- T_d = 4.75 / 2 = 2.375 hours
Calculating Walking Time
Now, substituting T_d back into the first equation:
- T_w + 2.375 = 6.75
- T_w = 6.75 - 2.375 = 4.375 hours
Total Time Walking Both Ways
The time taken to walk both ways is:
- Total walking time = 2 * T_w = 2 * 4.375 = 8.75 hours
Converting 8.75 hours into hours and minutes gives:
- 8 hours and 45 minutes
Thus, the time it would take for Amit to walk both ways is 8 hours and 45 minutes.
Final Answer
- The correct option is D: 8h 45min.
