Answer:
60 mph
Step-by-step explanation:
Time:miles
4:240
1:x
To get x divide 240 by 4 because that's what we divided 4 by to get 1
The rate is 60
select all times with the rate of 60 mph
15 + 1 because you are using apsolute value so that negative 1 becomes a positive
D1 = 60 for a price of $80. Charging $80 will ensure supply exceeds demand.

You divide 10 by 5 is two so 19 decided by five is 3.8
