C. The temp at 10pm was 6°C. Over the next 3 hours, the temp dropped 2°C/hr.
6 -2(3) = 0
Let a be the first term and d be the common difference
t5 = 3 = a + 4d
t7 = 7 = a + 6d
a + 6d - a - 4d = 7 - 3
2d = 4
d = 2
Sub d = 2,
3 = a + 4(2)
a = -5
t2 = a + d
t2 = -5 + 2
t2 = -3
Sal: 25 +5x = 240
Divide 5 from both sides so it would be 5+ x=240/5
Subtract 5 from both sides x=48-5
X= 43
Elena: 15 + 5x=300
Divide 5 from both sides so it would be 3 +x=300/5
Subtract 15 from both sides x=60-3
X=57
So Sal jogged for 43 minutes. While Elena jogged for 57 minutes
