Question

The time spent for various activites are given in the form of a pie chart below. Predict the total time spent for walking if totally 45 hours are spent for all the activities in a week.

• A. 10 hours
• B. 6 hours
• C. 15 hours
• D. 20 hours

Answer 1

The correct option is B 6 hours

From the pie chart, we can see:
Total time spent on all activities = 5 + 2 + 3 + 1 + 4 = 15

Experimental probability for time spent
$\text{for walking}=\frac{2}{15}$

It is given that, the total hours spent for all the activities = 45 hours

∴ Number of hours spent for walking = $\frac{2}{15}\times 45=6$

Hence, the predicted total time spent for walking = 6 hours.
