You are looking for a speed in miles per hour, so start by converting 90 minutes into hours.

90/60 = 1.5

90 minutes = 1.5 hours

speed = distance/time = (105 miles)/(1.5 hours) = 70 mph

Consider two markets: the market for cat food and the market for dog food. The initial equilibrium for both markets is the same,

umka21 [38]

Answer:

elasticity supply of dog food = 2.61

elasticity supply of cat food = 1.71

Step-by-step explanation:

The midpoint formula for elasticity is:

$Elasticity = \frac{(Q2-Q1)/[(Q2+Q1)/2]}{(P2-P1)/[(P2+P1)/2]}$

Point 1: Q = 39.0 and P = 5.50

Point 2: Q = 101.0 and P = 7.75

$Elasticity\ supply\ of\ dog\ food = \frac{(101.0-39.0)/[101.0+39.0)/2]}{(7.75-5.50)/[(7.75+5.50)/2]}=2.61$

Doing the same for the cat food:

$Elasticity\ supply\ of\ cat\ food = \frac{(71.0-39.0)/[71.0+39.0)/2]}{(7.75-5.50)/[(7.75+5.50)/2]}=1.71$
