Step-by-step explanation:
Angle pair 1 and 8
and
Angle pair 2 and 7
1 hour = 60 minutes, so 3 hours = 3 * 60 = 180 minutes.
Her total time was 3 hours and 28 minutes, so 180 + 28 = 208 minutes.
Divide her total time by total miles run:
208 minutes / 26 miles = 8 minutes per mile.
Combine like terms the variables first. 4b-15b=-11b
-7+3=-4
-11b-4
