Doug entered a canoe race. he rowed 3 1/2 miles in 1/2 hour. what is his average speed in miles per hour ?

Doug's average speed is 7 miles per hour.

Step-by-step explanation:

Average speed is defined as ratio of total distance to the total time taken to cover the total distance.

Distance covered by Doug ,D=

Time taken to cover the distance D = T=

Average speed :

Doug's average speed is 7 miles per hour.

im sorry but no. i just need to answer for 50 poonts oof

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
