Question

Please set up the boxes and help solve.

Answer 1

Let x be the hours driving out.
So, the distance out is 40*x, which must be equal to the distance back 30*(7-x)
40*x = 30*(7-x). Solve for x, and the rest will fall in place.

Answer 2

20

Answer 3

the answer is 240mph
explanation: 4 and 3 has a similar multiple and that is 12 meaning the question said 7 hours and he traveled 40mph to go to his destination and to go back was 30mph meaning to go to his destination it took 3 hours=120mph and to go back took 4 hours=120mph as well because to go to his destination he traveled 40mph and to go back was 30mph
