Total Time Taken = Distance Traveled / Speed So, Time = 60 / 40 hours = 3 / 2 hours = 1.5 hours So, the final answer is --> it will take 1.5 hours for her to reach the lake.

[latex]40\ \frac{miles}{hour} \cdot \frac{1hour}{60minutes} = \frac{40}{60} = \frac{2}{3} \ \frac{ mile}{minute} \\ \\ Now \ that \ we \ have \ the \ speed \ in \ \frac{ miles}{minute} , \ when \ we \ calculate \ the \ time, \\ \\ it \ will \ also \ be \ in \ minutes \\ \\ time = \frac{distance}{speed} \\ \\ time=\frac{60}{\frac{2}{3}}= 60 :\frac{2}{3}= \not60 ^{30} \cdot \frac{3}{\not2^1}= 90 \ minutes \\ \\ Answer : \ Rene \ gets \ to \ the \ lake \ for \ 90 \ minutes [/latex]
