Sierra walks her dog Pepper 2 times a day. Her evening walk is 2 and a half times as far as her morning walk. At the end of the week she tells her mom i walked Pepper 30 miles this week. How long is her morning walk?
Answer provided by our tutors
we will assume Sierra walks her dog Pepper 2 times a way, seven days per week
x = the length of the morning walk
2.5x = the length of the evening walk
x + 1.5x = 3.5x = the length of the walk per day
considering the 7 days per week the total is:
7*3.5x = 30
by solving we find:
x = 1.22 mi
