Answer:
132 minutes
Step-by-step explanation:
1 Km = (60)(8)+15=495 seconds
4 mornings = (495)(4) =1980 seconds
4 weeks = (1980)(4) = 7920 sec.
7920/60 = 132 minutes
Multiply both sides of your equation bye the denominator
Subtract 1 to 13. so you got 12. divide 4 so you can get the S by it self.S=3.
