Step-by-step explanation:
Average speed (S) = 200 m/s
Time taken (t) = 2 .5 hours = 2.5 *60*60 = 9000 sec
Now distance travelled (d) = ?
We know
The distance travelled by a body per unit time is
speed so
S = d / t
200 = d / 9000
d = 9000 * 200
d = 1800000 meters.
The plane flies 1800000 meters.
Supplier B would cost $600 more than supplier A. Then the correct option is B.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
A food production company is choosing between two suppliers of grain.
Let y be the cost and x be the number of bushels.
Supplier A sells grain for $5.25 per bushel plus a delivery fee of $3 per bushel.
y₁ = (5.25 + 3)x
y₁ = 8.25x
Supplier B sells the grain for $6.50 per bushel plus a flat delivery fee of $1,500 each week.
y₂ = 6.5x + 1500
Then the supplier would cost more if the production company bought 500 bushels of grain each week will be
For supplier A, we have
y₁ = 8.25 × 500
y₁ = $ 4125
For supplier B, we have
y₂ = 6.5 × 500 + 1500
y₂ = $ 4750
Then we have
y₂ - y₁ = 4750 - 4125
y₂ - y₁ = $ 625
Then the correct option is B.

A.) (2, 10), add -6 to -2 to give you 4 units. Then add 4 to the midpoint(-2, and 7), and you end up with 2 and 3. Then just add 3 to seven and you have the coordinates of (2, 10), hope this helps!
