I don’t speak Spanish but that is the answer.
Rosita’s answer is incorrect. It should be 42.
REASON:
429-387 is equal to 42 not 162
Answer:
the answer to the first one is A
the second one is 2
the last one is A
Answer:
(a)
(b)
The distance traveled in 30 seconds is 45 miles
(c)
It takes 85 seconds to go 12.75 miles
Step-by-step explanation:
we are given
An airplane is flying from New York City to Los Angeles
d is the distance traveled in miles
t is time in second
we have equation as
(a)
we have to find speed
we can see that our distance equation is in linear form
For finding speed, we can compare our equation with equation of line
and slope of the line will be speed
because slope is the rate of change
where m is slope
so, we can compare
and we get
so,
(b)
we can plug t=30 and find d
miles
so, The distance traveled in 30 seconds is 45 miles
(c)
we can set d=12.75 and solve for t
So,
It takes 85 seconds to go 12.75 miles
