Answer:
148
Step-by-step explanation:
The answer is 40mph because
Explanation
The rate of speed formula is r=d/t
So I just plug in the numbers into the formula and got my answer.
50miles /1.25hours = 40mph
3(4h+3d=18.25)-2(6h+4d=26.50)
12h+9d-12h-8d=54.75-53
d=1.75, use either original equation to solve for h...
4h+3(1.75)=18.25
4h+5.25=18.25
4h=13
h=3.25
So the cost of one hamburger and one drink is:
3.25+1.75=$5.00
