Koto is walking at a velocity of 4.5 m/s south. she started at her house and traveled 15000 meters north, 5000 meters east, 20000 meters south, and then 5000 meters west. what is her time based on her velocity? (there are 60 seconds in 1 minute.) 18.5 minutes 20.4 minutes 2 hours 3 hours

answer;

18.5 seconds

explanation;

velocity is distance covered per unit time; it is given by displacement divided by time.

thus; time = displacement/velocity

total time = total displacement/velocity

total distance = 5000 meters south

total time = 5000/4.5

                  = 1111.11 seconds

but; 1 minute = 60 sec

thus; 1111.11 /60

                = 18.51 seconds

thus; the time taken is 18.5 seconds

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
