Answer 2

Calculating the Total Time the Skier Spent Skiing

To calculate the total time the skier spent skiing over the three days, we can follow these steps:

1. Convert the Time from Mixed Numbers to Improper Fractions: - The skier was in transit for 5 hours and 3/12 hours on the first day, which can be converted to an improper fraction. - The skier was in transit for 2 hours and 8/12 hours on the second day, which can also be converted to an improper fraction. - The skier was in transit for 1 hour and 11/12 hours on the third day, which can be converted to an improper fraction.

2. Add the Total Time Spent Skiing: - Add the converted times from the three days to find the total time the skier spent skiing.

Conversion of Mixed Numbers to Improper Fractions

The time spent by the skier on each day can be converted to improper fractions as follows:

- First day: 5 hours and 3/12 hours = 5 + 3/12 hours - Second day: 2 hours and 8/12 hours = 2 + 8/12 hours - Third day: 1 hour and 11/12 hours = 1 + 11/12 hours

Calculation of Total Time Spent Skiing

To find the total time the skier spent skiing, we can add the converted times from the three days:

5 + 3/12 + 2 + 8/12 + 1 + 11/12

This will give us the total time the skier spent skiing over the three days.

Let's calculate the total time spent skiing.
