Answers
Answer:
Lily has to walk 4miles more.
Time taken to walk 1 mile = 60/3
=20 mins
Time taken to walk 4 miles = 20 × 4
=80
=80/60hours
= 1 hour 20 minutes
Given : Lily has walked 2 miles.
Her goal is to walk 6 miles.
Lilly plans to reach her goal by walking 3 miles each hour h for the rest of her walk
To Find : an equation to find the number of hours it will take Lily to reach her goal
Solution:
Lily has walked 2 miles.
Her goal is to walk 6 miles.
Miles left to walk = 6 - 2 = 4 miles
Lilly plans to reach her goal by walking 3 miles each hour
Let say she walks for h hours
Distance covered in h hrs = 3h miles
Equate with miles left to walk
=> 3h = 6 - 2
3h = 6 - 2 is the required equation:
3h = 4
=> h = 4/3
Hence 4/3 hrs = 1 hr 20 minutes
