Question

Tommy starts walking from school to home at the same time that his Dad starts walking from home to school. They both depart at 3:00 p.m. Tommy is walking at a speed of 1.35 meters per second, and his Dad is walking at a speed of 1.65 meters per second. The distance between home and school is 720 meters. At what time will they meet?

Answer 1

They will meet at 3:04 p.m

Explanation:

Since they are walking towards each other , that means we should add their speed together:

speed = 1.35 m/s + 1.65 m/s
= 3 m/s

Now that we have found the speed, we can calculate the time:

time = 720 meters / 3 m/s
= 240 seconds
= 4 minutes ( 240 seconds is 4 minutes)
