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.
You would do 200 times 1.58 and that gets you 316 hope this helps :)
Answer:
5.52%
Step-by-step explanation:
there is a 5.52% chance of it not improving you do 69% of 8 and that determines if its not gonna get better.
Answer: A) 18.3 x 7 and D) 5.4 x 2.8
Step-by-step explanation:
A) 18.3 x 7 = 128.10
We can infer that 1 is in the tenths place.
B) 6.5 x 4.31 = 28.015
We can infer that 1 is not in the tenths place but rather the hundredths place.
C) 8.54 x 2.3 = 19.642
We can infer that 1 is not in the tenths place.
D) 5.4 x 2.8 = 15.12
We can infer that 1 is in the tenths place.
