Anton's family drove 216 mi to the lake averaging 48 mi/h . on the return trip home they averaged 54 mi/h . what was the total time that anton's family spent driving to and from the lake? 8.0 h 8.5 h 9.0 h 9.5 h

For this case we have that the distance that it is necessary to cross to arrive at the lake is of 216 miles.

If the family went there with an average of

To know the time it took me to travel 216 miles, we make a rule of three:

Let "x" be the time spent going to the lake:

48 miles -------------> 1 h

216 miles -----------> x

Thus, to reach the lake they had to travel 4.5 hours.

Now, back home they averaged

To know how much time they used back home, we make a rule of three (to return also travel 216 miles):

Let "y" be the time spent returning home:

54 miles -------------> 1 h

216 miles -----------> y

Thus, the total time is given by:

8.5 hours

Option B

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
