Given market demand Qd=50-p, and market supply p=Qs+5.what would be the state of the market if market price was fixed at Birr 25

Lemur [1.5K]

The state of the market if market price was fixed at Birr 25 per unit is excess demand

<h3>Quantity demanded</h3>

Qd = 50 - p

p = Qs + 5

p - 5 = Qs

if market price was fixed at Birr 25 per unit?

Qd = 50 - p

= 50 - 25

Qd = 25

Qs = p - 5

= 25 - 5

Qs = 20

The state of the market if market price was fixed at Birr 25 per unit is excess demand (demand greater than supply) leading to an increase in price.

pav-90 [236]

Answer:

11.1m/s

Step-by-step explanation:

Given parameters:

Distance of store = 5miles

Time to store = $\frac{1}{2}$ hr

Time from store = $\frac{2}{5}$ hr

Unknown:

Average speed = ?

Solution:

Average speed is the total distance divided by the total time taken.

Average speed = $\frac{total distance}{total time taken}$

Total distance = distance to store + distance from store = 5 + 5 = 10miles

Total time taken = $\frac{1}{2}$ hr + $\frac{2}{5}$ hr = $\frac{9}{10}$ hr

Average speed = $\frac{10}{\frac{9}{10} }$ = 10 x $\frac{10}{9}$ = 11.1m/s
