Elaine walks her dog 2 times a day. Her walk in the evening is 2.5 times as far as her morning walk. At the end of the week she walked the dog 30 miles. How long is her morning walk?

Sagot :

Answer:

Step-by-step explanation:

If we let w represent the length of the morning walk, Sierra walks w+2.5w or 3.5w miles each day.

At the end of the week, she has walked 7 times as far and she said that this was 30 miles.  

24.5w=30,

we have w=30/24.5≈1.2 miles. Therefore the distance of Sierra's morning walk is about 1.2 miles
