Jimmy drove to his cabin on the lake and back. it took 0.6 hours longer to go there than it did to come back. the average speed on the trip there was 46 km/h. the average speed on the way back was 52 km/h. how many hours did the trip there take

9.8 hours

Step-by-step explanation:

Let the distance be x km

T1 be time taken to go to trip

T2 be time taken to go back trip

Time =

Average speed on way of trip = 46 km/h

T1 =

Average speed on the way back = 52 km/h

T2 =

According to question

T1-T2 = 0.6

-= 0.6

=0.6

3x=1196×0.6

3x=717.6

x=

x=239.2 km

T1=

T1=5.2 hour

T2=

T2=4.6 hour

Total time taken to complete the trip = T1+T2

Total time = 5.2+4.6 =9.8

Hence the correct answer is 9.8 hours

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
