Answer 1

Answer:

1. 10724.2857143

2.

(a) Miguel

(b) I don't know

Step-by-step explanation:

1. 10150 + 10211 + 10424 + 10769 + 10884 + 11155 + 11477 = 75070

75070/7 = 10724.2857143

2a.

ADAM: Least no. of seconds - 91

ADAM: Greatest no. of seconds - 106

106 - 91 = 15

MIGUEL: Least no. of seconds - 85

MIGUEL: Greatest no. of seconds - 105

105 - 85 = 20

20>15
