Answer:
40 mph
Step-by-step explanation:
We assume "outbound" refers to the trip <em>to the lake</em>. The ratio of speeds is inversely proportional to the ratio of times, so ...
outbound speed : inbound speed = 4 : 3
These differ by one ratio unit, so that one ratio unit corresponds to the speed difference of 10 mph. Then the 4 ratio units of outbound speed will correspond to ...
4×10 mph = 40 mph
Paul's average speed on the outbound trip was 40 mph.
___
The distance to the lake was 120 mi.
A cuboid has 8 vertices and 12 edges
Answer:
140
Step-by-step explanation:
180 - 120 = 60 (angle3)
180-100 = 80 (angle 2)
180 - (60 + 80 ) = 40 (angle 1)
180- 40 = 140
Area= length * width
Therefore, you do 3*1/8
ie 3/8
idk if its right :/
