Answer:

5 minutes

Step-by-step explanation:

To get the response to this question, it would be required to convert both times to seconds alone.

For the first, the time It takes to flash is 1 minute 15 seconds which is same as 75 seconds

For the second, it takes 1 minute 40 seconds which is same as 100 seconds.

Now to get the time they would flash together, we need to know their lowest common multiples. The values involved are 75 and 100. Thus, the lowest common multiple of both is 300.

This is equivalent to 300 seconds which is 5 minutes time

A truck rental is $25 plus $ 0.40/mi find out how many miles ken traveled if his bill is $59.40
Zanzabum

Answer:

Step-by-step explanation:

C = 59.4

Fixed Cost (F) = 25

C = 25 + 0.4*x                    Solve for x

59.40 = 25 + 0.4x              Subtract 25

34.4  = 0.4x                        Divide by .4

34.4/0.4 = x

x = 86 miles
