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?

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

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
