Iwill be giving a family is driving 600 miles. assuming they stop to get gas 3 times and eat 2 times, how many hours will it take them to reach their destination? how would you estimate the time? you earn points for showing work.

In order to estimate the time it takes for them to travel 600 miles (without interruption), you can divide 600 miles by their velocity or Mph (not given).

Also an approximation of the time they would have spent eating and refueling could be calculated if the information was available.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,

mrb

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
