Answer:
6.4 minutes
Step-by-step explanation:
The question gave us the following details:
Average speed = 60mph
Time spent on trip = 8 hours
Average speed of express train on way back = 75mph
T = distance/speed
D = distance
V = speed
T = d/v
d = v(t)
d = 60 x 8
= 480
Such that
480/75
= 6.4 hours.
That is 6 hours 40 minutes is the length of time it would take on the trip home.
Thank you!
Answer: 11 units
Step-by-step explanation:
Use the distance formula: 
Answer:
(x, y) = (6, -9)
Step-by-step explanation:
Add the two equations to eliminate the y-variable:
(3x +5y) +(-7x -5y) = (-27) +(3)
-4x = -24 . . . simplify
x = 6 . . . . . . divide by -4
Substitute this value of x into the first equation and solve for y:
3(6) +5y = -27
5y = -45 . . . . . . . subtract 18
y = -9 . . . . . . . . . divide by 5
The solution to this system of equations is (x, y) = (6, -9).
Answer:
Hi I think the answer would be D
