Rying to be on time for class, a girl moves at 2.4 m/s down a 52 m-long hallway, 1.2 m/s down a much more crowded hallway that is 79 m long, and the last 25 m to her class at 3.4 m/s. how long does it take her to reach her class?

Respuesta :

The calculated time is 16 minutes. In physics, the definition of time is simple. Time is the interval at which changes or changes occur.

If nothing changes, you never know how much time has passed. Changes in length or time are calibrated by comparison to a standard. The SI unit of time is seconds, abbreviated s.

speed = distance/time or distance = speed * time

time to time conversion = 40/60 time

task,

distance = 12 * (40/60) => 8 km

Now you know the distance from her to the school.

again:

time = distance/speed
