Question

A plane is flying to Metro City. The plane started its journey 1275 miles from Metro City.

Answer 1

Answer:

550a + 590b = 1275

Step-by-step explanation:

We use the following relation to solve this question:

$v = \frac{d}{t}$

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:

$d = v*t$

A plane is flying to Metro City. The plane started its journey 1275 miles from Metro City.

This means that $d = 1275$.

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 $v*t = 550a + 590b$.

Which equation is correctly written in standard form to represent this scenario?

$d = v*t$

1275 = 550a + 590b

550a + 590b = 1275
