Answer:
x = and y =
Step-by-step explanation:
Known that he sum of angles on a straight line is . From the diagram;
2y + x + y =
x + 3y = ................ 1
Also,
2x + x + 2y =
3x + 2y = .............. 2
Using the elimination method, multiply equation 1 by 3 and equation 2 by 1
3x + 9y = 540 ............ 3
3x + 2y = ............. 4
7y = 360
y =
y =
substitute the value of y in equation 1,
x + 3y =
x + 3(51.4) =
x + 154.2 =
x = - 154.2
x =
Thus, x = and y =
The answer is: " 105 mi. " .

Note that: "that amount of time" is "3 hours".
→
= ? ;
→ The units of "h" (for "hour/s") cancel out to "1" ; since ("h/h = 1") ;
→ and we are left with (35 * 3) mi. = 105 mi.
