Calculating the Total Time for the Tourist Route

To calculate the total time taken for the tourist route, we can add the time taken for uphill, downhill, and on the plain.

- Time taken uphill: 2 1/4 hours - Time taken downhill: 3/5 hours less than uphill - Time taken on the plain: 11/20 hours

Let's calculate the total time taken for the tourist route step by step.

Time Taken Uphill

The time taken uphill is given as 2 1/4 hours.

Time Taken Downhill

The time taken downhill is 3/5 hours less than the time taken uphill. We can calculate this as follows: 2 1/4 - 3/5 = 2 1/4 - 1 1/5 = 1 1/5 hours

Time Taken on the Plain

The time taken on the plain is given as 11/20 hours.

Total Time Taken

To find the total time taken for the tourist route, we can add the time taken uphill, downhill, and on the plain: 2 1/4 + 1 1/5 + 11/20

Let's calculate the total time.
