Answer:

126 minutes or 2 hours and 6 minutes

Step-by-step explanation:

Find how long it took her to swim one lap

1 hour and 30 minutes = 90 minutes

90/5 = 18

This means it took her 18 mins to swim each lap

18 · 7 = 126

It took her 126 minutes/2 hours and 6 minutes to swim 7 laps

1. Jill had the following scores on quizzes. 1 quiz: 1 3 quizzes: 2 4 quizzes: 3
Irina-Kira [14]
The mean score is 3.08.

There is 1 quiz with score 1, so 1 point; 3 quizzes with score 2 for 3*2 = 6 points; 4 quizzes with score 3 for 4*3 = 12 points; 4 quizzes with score 4 for 4*4 = 16 points; and 1 quiz with score 5 for 5 points.

This is a total of 1+6+12+16+5 = 40 points.

This is out of 1+3+4+4+1 = 13 quizzes.

40/13 = 3.08
