Answer:
169
Step-by-step explanation:
125+263=388
388-557+169
This should be the correct work for the questions. You set the angle measures equal to each other because they are corresponding, alternate interior, and alternate exterior.
Let the first car travel east (to the right) and the second car west (to the left). Call the distances traveled e and w respectively.
The first car starts out an hour before the second car (that is, at hour 0), traveling at 55 mph. During the first hour, this car travels 55 miles east. A general equation for the distance traveled from the starting point as a function of x (time) is e=(55 mph)(1 hour) + (55mph)x
The other car starts out at time = 1 hour, at 75 mph. A general equation for the distance traveled from the same starting point as a function of x is then w = (75 mph)x.
We want to know when the total distance traveled in opposite directions by the two cars is e + w = (55 miles) + (55 mph)x + (75 mph)x = 380 mi
Solve for x. 55 miles + (55+75)(mph)x = 380 miles
(130 mph)x = 325 miles
Divide both sides by (130 mph):
(130 mph) x 325 miles

(130 mph) 13 mph
