<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.
in case you wonder why we used 105 as LCD,
21 = 3 * 7
15 = 3 * 5
the "3" is common to both denominators, so we "use it once" and our LCD is then 3 * 7 * 5.
