Add the two trips together for total Km’s:
4500 + 11700 = 16,200 km.
divide total km by speed:
16,200 / 1,100 = 14.727272 hours
0.727272 x 60 minutes per hour = 43.636363 minutes, round up to 44 minutes
total time: 14 hours and 44 minutes
I think the answer is 180 not sure though :)

Answer:
50 mph
Step-by-step explanation:
The total distance is 350 miles.
The total time is 3 hr + (240 mi / 60 mph) = 7 hr.
The average speed is 350 mi / 7 hr = 50 mph.

Answer:
y = x + 7
Step-by-step explanation:
The line has a "rise" of 1 grid square for each "run" of 1 grid square to the right. (It passes through successive grid intersections.) This means it has a slope of ...
m = slope = "rise"/"run" = 1/1
m = 1
The line crosses the y-axis at y = 7, so the y-intercept is ...
b = 7
Then the slope-intercept form equation is ...
y = mx + b
y = x + 7
