Two trucks started traveling from the same place at 9: 00 a. m. one truck traveled north going 45 mph and the other traveled south going 50 mph. what time will it be when the trucks are 380 miles apart?

Short Answer 1 PM
Givens
South bound truck's rate = 50 mph
North bound truck's rate = 45 mph
Distance apart = 380 after time t
The time that passes = t

Equations
d = r * t
d1 + d2 = 380
d1 = r_south * t 
d2 = r_north * t

Substitute and solve.
r_south * t + r_north * t = 380
50*t + 45*t  = 380 Combine like terms.
95t = 380  Divide by 95
t = 380 / 95
t = 4 hours

Answer
t = 9:00 + 4 hours = 1300 hours = 1:00 PM  <<<< answer

D) the x-intercept represents adam's commission pay when he had zero total sales

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
