Answer: Larry spends a total of 54 days traveling to Japan in one year for business.
Step-by-step explanation: Assuming each round trip takes 18 hours in both directions, Larry spends a total of 36 hours for each round trip to Japan.
To calculate the total number of days he spends traveling to Japan in one year, you can use the following steps:
Calculate the total number of hours Larry spends traveling to Japan in one year:
Total hours = 3 round trips/month * 12 months/year * 36 hours/round trip
Total hours = 3 * 12 * 36 = 1,296 hours
Convert the total number of hours to days:
1 day = 24 hours
Total days = Total hours / 24 hours/day
Total days = 1,296 hours / 24 hours/day
Total days = 54 days
Therefore, Larry spends a total of 54 days traveling to Japan in one year for business.
