Arunner circles the track exactly 2 times for distance of 800m. it takes 4.0min. what is her average speed in m/s? what is her average velocity?

Calculation of average speed:

we are given

A runner circles the track exactly 2 times for distance of 800m

so, distance is

d=800m

it takes 4.0min

so, t=4min

we know that

1min =60 sec

we can change time into seconds

now, we can use speed formula

now, we can plug it

and we get

ian gone lie this got me confused

step-by-step explanation:

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
