So lets say the distance one boy travels is 'x', you can set up an equation like this:
x + x + 1 = 7
2x +1 = 7
2x = 6
x = 3
So one boy walks 3 miles in one hour, and the other walks 4 miles in one hour.
Therefore, their speeds are 3 miles per hour and 4 miles per hour respectively.

Answer:
The correct option is A
Step-by-step explanation:
The question is incomplete because the options are not given for the question. Lets complete the question first. The options for this question are given below.
A) (-1)(7+7+7)
B) (-7)+(-7)+(-7)+(-7)
C) 7+7+7
D) 7+7+7+7
Now look at the conditions given. Supoose at 4pm, the temperature is x°F at 4pm. As temperature is decreasing 7°F every hours, and it happenss for 4 hours.
We can say that after one hour, temperature is:
5pm: x°F - 7°F
After two hours:
6pm: x°F - 7°F - 7°F
After three hours:
7pm: x°F - 7°F - 7°F - 7°F
Hence, the expression is given by:
-7 - 7 - 7
or
(-1)(7+7+7)
