Two friends leave their houses at the same time and run across town towards each other. The first friend runs at a speed of 8 miles per hour. The second friend runs at a speed of 7 miles per hour. If they left at 6 p. m. and their houses are 20 miles apart, at what time will they meet?

They will meet at 7:17

Step-by-step explanation:

The second friend is slower so by the time she gets there the first friend will already be there. Therefore, since 60 divided by 7 simplified is 8 multiplied by 2 adds 17 minutes to that hour.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

the answer is a.

135 and 80
