A, here's the step by step where B... base and h... height
Answer:
d = 45t
Step-by-step explanation:
<u>Define the variables</u>:
- Let d = distance traveled (in miles)
- Let t = time (in hours)

Therefore, if the train traveled at a constant speed (k) then:

where k is some constant to be found.
Given:
- d = 67.5 miles
- t = 1.5 hours
Substitute the given values into the formula and solve for k:

Substitute the found value of k into the equation thus creating an equation that shows a proportional relationship:

Answer:
$40 per hours
Step-by-step explanation:
Divide 80/2, that gives you 40. Divide 160/4 that also gives you 40
A) 8500 times 0.3 = 2550
B) 15600 = 0.3x
X=15600/0.3=52000
