Tommy and his father will meet after 2400 seconds or 40 minutes. So they will meet at 3:40 pm.

What is speed?

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.

Given that:-

  • Tommy starts walking from school to home at the same time that his dad starts walking home to school they both depart at 300pm Tommy is walking at a speed of 1.35meters 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

The time will be calculated by using the relative speed concept.

Relative speed = Speed of father - Speed of Tommy

Relative speed = 1.65 - 1.35

Relative speed = 0.3 meter per second

Relative speed = Distance / Time

0.3 = 720 / Time

Time = 720 / 0.3

Time = 2400 seconds = 2400/ 60 = 40 minutes

We know that both departed at 3 pm they will meet at 3:40 pm.

Therefore Tommy and his father will meet after 2400 seconds or 40 minutes. So they will meet at 3:40 pm.

Answer:

They will meet at 3:04 p.m

Step-by-step explanation:

Since they are walking toward 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)
