<u>Step 1: Assign variable for the unknown that you need to find. </u>
Let ' t ' be the number of hours it took for the pedestrians to meet.
<u>Step 2: List the give details</u>
Speed of first pedestrian = 4 km/hr.
Speed of second pedestrian = 6 km/hr.
Distance between two pedestrians = 27 km.
<u>Step 3: Set up an equation</u>
The relationship between speed, distance and time is given below:
The first one walked 4 km per hour, distance traveled by first pedestrian is given below:
Two pedestrians simultaneously left two villages 27 km apart and walked toward each other.
Conclusion:
The pedestrian meet after 2.7 hours.

Answer:
Diego will finish first while Lin and Elena would finish reading their book at the same time
Step-by-step explanation:
Rates Lin, Diego, and Elena are competing to see who can finish their book the fastest.
Their rates is calculated as:
For Lin
Lin read the first 54 pages from a 270-page book in the first 3 days.
54 pages = 3 days
270 pages = x
Cross Multiply
54x = 270 × 3
x = 270 × 3/54
x = 15 days
For Diego
Diego read the first 100 pages from a 320-page book in the first 4 days.
100 pages = 4 days
320 pages = x days
Cross Multiply
100x = 320 × 4
x = 320 × 4/100
x = 12.8 days
For Elena
Elena read the first 160 pages from a 480-page book in the first 5 days.
160 pages = 5 days
480 pages = x days
Cross Multiply
160x = 480 × 5
x = 480 × 5/160
x = 15 days
If they continue to read every day at these rates, who will finish first, second, and third?
Diego will finish reading his book first while Lin and Elena would finish reading their book at the same time
