We'll represent the distance as d and the time as t.
d= 3(t+7) because Gilda is 7 minutes late when travelling 3 mph
d= 4(t-5) because Gilda is 5 minutes early at 4 mph
d= 3t + 21
d= 4t -20
3t +21 =4t -20
41=t
d= 3(41) +21= 144
The distance is 144 miles.

Answer:

Step-by-step explanation:
The
-intercept of a line is the
value when
. In the equation
, we can solve for its equation when we plug in
.
Solving for
when
:
.
So the
-intercept of the equation
is
.
To find what equation has the same
-intercept, we can do the same process for each equations given by the choices. However, I can see that the equation,
, has the
-intercept. If in doubt, you can check for the solution below or solve each equations for yourself.
Solving for
when
:
