On a certain nonstop trip, marta averaged x miles per hour for 2 hours and y miles per hour for the remaining 3 hours. what was her average speed, in miles per hour, for the entire trip?

Average speed = (2x+3y)/5 miles/hour

Explanation:

Average speed is the total distance travelled per unit time.

Average speed = total distance/total time taken

Given;

1. Travelled x miles per hour for 2hours.

2 travelled y miles per hour for 3 hours.

Distance covered is;

1. Distance = speed × time

d1 = x × 2 = 2x

2. d2 = y × 3 = 3y

Total distance travelled = d1+d2 = 2x + 3y

Total time taken = t1+t2 = 2+3 = 5hours

Average speed = (2x+3y)/5 miles/hour

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
