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
