Answer

Explanation:

Step1: Calculate Jacqueline's total practice - time

Add up her session times: $40 + 35+45 + 30=150$ minutes.

Step2: Calculate Jacqueline's average practice - time

She practiced 4 times, so the average is $\frac{150}{4}=37.5$ minutes.

Step3: Calculate Cassie's total practice - time

Add up her session times: $15 + 30+15 + 15+50 = 125$ minutes.

Step4: Calculate Cassie's average practice - time

She practiced 5 times, so the average is $\frac{125}{5}=25$ minutes.

Step5: Calculate the difference in Jacqueline's longest and shortest sessions

Her longest is 45 minutes and shortest is 30 minutes, so the difference is $45 - 30 = 15$ minutes.

Step6: Calculate the difference in Cassie's longest and shortest sessions

Her longest is 50 minutes and shortest is 15 minutes, so the difference is $50 - 15 = 35$ minutes.

Step7: Identify the greatest practice - time

Jacqueline's longest session is 45 minutes and Cassie's longest session is 50 minutes.

Answer:

The difference in length between Cassie's longest and shortest practice sessions was greater than the difference in length between Jacqueline's longest and shortest sessions.
