Explanation:

Problem 5:

Step1: Calculate total percentage of car and train

Total percentage of car and train = 37% + 42.5% = 79.5%

Step2: Calculate percentage of bus journey

Percentage of bus journey = 100% - 79.5% = 20.5%

Step3: Calculate distance traveled by bus

Distance by bus = 403 km × (20.5/100) = 403 × 0.205 = 82.615 km

Step1: Calculate percentage of plastic bottles

Percentage of plastic bottles = (Number of plastic bottles / Total number of bottles) × 100% = (19 / 50) × 100% = 38%

Step1: Calculate number of glass bottles

Number of glass bottles = Total number of bottles - Number of plastic bottles = 50 - 19 = 31

Step2: Calculate percentage of glass bottles

Percentage of glass bottles = (Number of glass bottles / Total number of bottles) × 100% = (31 / 50) × 100% = 62%

Answer:

The distance traveled by bus is 82.615 km.
