To calculate the total number of hours Jenna trains without her Wednesday practice, we need to add up the hours for the other days:
Sunday: 1 1/2 hours
Monday: 1 hour
Tuesday: 2 1/2 hours
Thursday: 2 hours
Friday: 1 1/2 hours
Saturday: 2 hours
Adding these up, we get:
1 1/2 + 1 + 2 1/2 + 2 + 1 1/2 + 2
This equals:
(1 + 2 + 2 + 1 + 2) + (1/2 + 1/2 + 2/2 + 1/2)
Now calculate the whole numbers and fractions separately:
Whole numbers: 1 + 2 + 2 + 1 + 2 = 8
Fractions: 1/2 + 1/2 + 2/2 + 1/2 = 2/2 + 2/2 = 1 + 1 = 2
Now add whole numbers and fractions:
8 + 2 = 10 hours
So, the total number of hours that Jenna trains, excluding Wednesday's practice, is 10 hours.
The correct answer is B) 10 hours.
