Answer:
550a + 590b = 1275
Step-by-step explanation:
We use the following relation to solve this question:
In which v is the velocity, d is the distance and t is the speed.
In this question, we find the distance, so we use:
A plane is flying to Metro City. The plane started its journey 1275 miles from Metro City.
This means that .
Write an equation in standard form to represent the situation if the plane travels a hours at 550 mph and b hours at 590 mph.
This means that .
Which equation is correctly written in standard form to represent this scenario?
1275 = 550a + 590b
550a + 590b = 1275

Answer:
About 20.8 minutes
Step-by-step explanation:
TO solve this just think of it as a ratio. The number of potatoes goes on top and the time goes on bottom.
48
__
10
That is what the first one would look like. In the second one we know the number of potatoes but we are trying to find the time (x).
100
___
x
Take these two ratios and set them equal to each other.
Next you cross multiply (take 48 times x and 100 times 10).
48x=1000 Now divide by 48 and you have your answer.
About 20.8 minutes
