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 ...

Answer:
The amount after 3 years of investment is $20763 .
Step-by-step explanation:
Given as :
The principal invested = p =$15,000
The rate of interest = r = 3% compounded annually
The time period = t = 11 years
Let The Amount after 3 years = $ A
<u>From Compounded method</u>
Amount = Principal × 
Or, A = p × 
Or, A = $15,000 × 
Or, A = $15,000 × 
Or, A = $15,000 × 1.3842
Or, A = $20763
So, Amount = A = $20763
Hence The amount after 3 years of investment is $20763 . Answer
