Eudora spent 0.5 hours from home to library and 1.5 hours from library to school

Step-by-step explanation:

Given

Home to Library:

-- Average Speed

Library to School

-- Average Speed

Total

Required

Determine the time taken from home to library and from library to school

Let the time spent from home to library  be x. So, from library to school will be: 2 - x

So, we have:

Home to Library:

-- Average Speed

-- Time

Library to School

-- Average Speed

-- Time

Distance is calculated as:

Home to Library:

Library to School:

The total distance is 120km. So, we have:

Collect Like Terms

Solve for x

Recall that:

So, we have:
