Question

Rene is going to the lake to visit some friends. If the lake is 60 miles away, and Rene is driving at 40 miles per hour the entire time, how long will it take her to get to the lake?

Answer 1

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

Answer 2

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.
