kiara enjoys rollerblading on paved trails. this graph shows how long she spent on different days. rollerblading times how much total time did kiara spend on the rollerblading trips that took her exactly 2 1/2 hours to finish? 3 hours 6 hours 7 hours 7 1/2 hours

Answer

Explanation:

Step1: Identify number of trips at $2\frac{1}{2}$ hours

Count the 'x's above $2\frac{1}{2}$ on the graph. There are 3 'x's.

Step2: Calculate total time

Each 'x' represents a trip of $2\frac{1}{2}=\frac{5}{2}$ hours. Multiply the number of trips (3) by the time per trip $\frac{5}{2}$ hours. So, $3\times\frac{5}{2}=\frac{15}{2} = 7\frac{1}{2}$ hours.

Answer:

$7\frac{1}{2}$ hours
