Question 551647: An angle is four times as large as its complement. Find the degree measure of each angle.
=========================================
Two automobiles start out from two points kilometers apart and travel toward each other. The automobile from the east travels at 10 kph faster than the automobile from the west. If they meet after 5 hours, what is the average speed of each automobile?

You can put this solution on YOUR website!
You have not given how many miles they are apart. I have asssumed 600 miles.
Just plug the distance and get your answer
Automobile I x mph
Automobile II x+ 10
..
They are moving towards each other

So add up their speed.

combined speed = x+x+10
(2x+10)
Time = 5 hours
Distance = 600 miles
Distance = speed * time =
(2x+10 )*5= 600
10 x + 50 = 600
10 x = 600 + -50
10 x = 550
/ 10
x= 55 mph Automobile I
Automobile II 55 + 10 = 65 mph
