Answer:
Step-by-step explanation:
7x + 8y + 5z
I put the equations in parentheses, assuming that I would be adding both of the equations together. Then, I removed them and combined the like terms. I used two calculators to check my answer, and this should be correct.
The total distance is 198 km
The rate is 36 km/h
The formula for the time of travel is
t = d / r
where t is the time of travel
d is the distance
r is the rate
Substituting,
t = 198 / 36
t = 5.5 h
The answer is 5.5 h.
