Answer:
2 hours 30 minutes
Step-by-step explanation:
Step one
Given data
The total distance to be covered= 20miles
Priya runs at a constant speed of 6 miles an hour
Hence Her speed = 6mph
Jada walks at a constant speed of 2 miles an hour
Hence Her speed = 2mph
let the time taken by them to cover the distance be t
Step two:
from speeed= distance/time
distance= speed*time
so
20=6*t+2*t
20= 6t+2t
20=8t
divide both sides by 8
t= 20/8
t=2.5 hours
That is, it wiil take them 2 hours 30 minutes to meet
The reason is because, the distances covered by them must sum up to 20 miles
In this question, <span>q is the number of buggies the company can sell in a month if the price is $p per buggy. The revenue should be number of buggies sold(q) multiplied by the price(p). The equation would be:
revenue= p * q
revenue= p * (-4p + 616)= -4p^2 + 616p
The maximum revenue should be in the peak of the graph. The calculation would be:
</span>-4p^2 + 616p
-4*2 p^2-1 + 616*1 p^1-1=0
<span>-8p + 616=0
8p= 616
p=77
Put p=77 in the revenue equation would result
</span>revenue= -4p^2 + 616p
revenue= -4(77^2) + 616(77) = -23716 + 47432= $23716
