Sierra walks her dog Pepper twice a day. Her evening walk is two and a half times as far as her morning walk. At the end of the week she tells her mom, "I walked pepper for 30 miles this week! How long is her morning walk?

Answer:1.71

Step-by-step explanation:If she walks every day divide 30 by seven to see how much she walks a day. 30/7≈4.28 divide by 2.5 to find out how much she walks in the morning 4.25/2.5=1.71. So she walks 1.71 hours in the morning
