Answer:
$3 per hour
Explanation:
Data provided in the question:
Cost of air travel, C = $300
Time for Air travel, T = 6 hours
Cost of bus ticket, c = $150
Time for bus ticket, t = 56 hours
Now,
The Extra amount paid for the air travel = $300 - $150
= $150
Time saved from the Air travel = 56 - 6 = 50 hours
Therefore,
The minimum value of one's time = [Cost paid] ÷ [Time saved ]
= $150 ÷ 50
= $3 per hour
