Runner a is initially 4.4 mi west of a flagpole and is running with a constant velocity of 7.5 mi/h due east. runner b is initially 3 mi east of the flagpole and is running with a constant velocity of 5.1 mi/h due west. how far are the runners from the flagpole when they meet? answer in units of mi.

Explanation:

Since two runners are moving towards each other and meet at distance "x" from flag pole then the distance covered by Runner A is given as

also we have distance moved by runner B is

now if they both meet at this position

so the time taken by both runners to reach this position must be same

so we will have

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

so easy. just google the electromagnetic waves and it’ll pop up.
