Two cars pass each other on a freeway at 6:30 a.m. The car driving north is traveling at an average speed of 60 mph and the car driving south is traveling at an average speed of 40 mph. At what time will they be 25 miles apart?

So the answer is 6:45?

that was so confusing

To find out at what time the cars will be 25 miles apart, we can use the formula:

Distance = Speed * Time

Let's assume that the time it takes for the cars to be 25 miles apart is t hours.

For the car driving north, we have:
Distance = Speed * Time
25 miles = 60 mph * t

For the car driving south, we have:
Distance = Speed * Time
25 miles = 40 mph * t

To find the time t, we can solve for t in either one of the equations. Let's solve it using the equation for the car driving south:

25 miles = 40 mph * t

Divide both sides of the equation by 40 mph:
25/40 miles = t

Simplify:
5/8 miles = t

Since we have found the value of t, which represents the time it takes for the cars to be 25 miles apart, we can now find the clock time.

Given that they passed each other at 6:30 a.m., we can add t hours to 6:30 a.m. to determine the clock time when they will be 25 miles apart.

If we convert the fraction 5/8 to a decimal, we get approximately 0.625. Adding this to 6:30 a.m. yields:

6.5 + 0.625 = 7.125 hours

Converting this back to clock time, we have:

0.125 hours * 60 minutes/hour = 7.5 minutes

Therefore, the cars will be 25 miles apart at approximately 7:07 a.m.

Thank you.

distance=rate*time

25=(60+40)t
t=.25 hr. add that to six thirty.
