Question

the chart shows the number of hours full - time college students spend participating in various activities during an average weekday. according to the graph, approximately how many hours do college students have available every weekday to devote to fitness? 1 to 2 hours 3 to 6 hours 7 to 8 hours 9 to 12

Explanation:

Step1: Calculate total hours in a weekday

A weekday has 24 hours.

Step2: Sum up non - fitness related hours

Sum of hours for traveling (1.0), other (3.3), grooming (0.8), eating and drinking (1.5), educational activities (6.4), working (3.0), sleeping (8.4) and leisure and sports (something not fitness). But wait, actually, we assume that the "leisure and sports" is the category where fitness could be. But if we consider that the total of all other categories: \(1.0 + 3.3+0.8 + 1.5+6.4+3.0+8.4\)

This is wrong. Wait, no, actually, the sum of all the given activities (assuming that the pie - chart represents all activities) is: \(1.0+3.3 + 0.8+1.5+6.4+3.0+8.4+(let\ leisure\ and\ sports\ be\ x)\). But since it's a pie - chart of 24 hours. If we assume that the "leisure and sports" is the time for fitness (a wrong assumption but given the data). Wait, no, actually, if we calculate the sum of all non - "leisure and sports" activities: \(1.0+3.3+0.8+1.5+6.4+3.0+8.4\)

$$1.0+3.3+0.8+1.5+6.4+3.0+8.4=(1.0 + 3.3)+(0.8+1.5)+(6.4+3.0)+8.4=4.3+2.3+9.4+8.4 = 24.4$$

(this is wrong due to rounding in the pie - chart). But if we assume that the "leisure and sports" is around 1 - 2 hours (by visual inspection of the pie - chart, as the slice for "leisure and sports" is small).

Answer:

1 to 2 hours
