Two friends live 7 miles apart. one saturday, the two friends set out on their bikes at 8 am and started riding towards each other. one rides at 0.2 miles per minute, and the other rides at 0.15 miles per minute. at what time will the two friends meet?my dear genius fellows i'm really dumb.

Step-by-step explanation:

Alright, lets get started.

Suppose they take t minutes to meet each other.

Distance covered by first friend in t minutes,

Distance covered by second friend in t minutes ,

Total distance is given as 7, so

means after 20minutes they will meet.

So, if they started at 8:00 AM, they will meet at 8:20 AM.

Hence the answer is 8:20 AM   :   Answer

Hope it will help :)

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
