I believe it's 192
Step-by-step explanation:
Let car b be travelling at x mph. as they are travelling towards each other their speed of approach is (x + x + 15 ) mph. So we have the equation
speed = distance / time
2x + 15 = 250 / 2
2x = 125 - 15 = 110
x = 55 mph
Car b travels at 55 mph and car a travels at 70 mph Answer
32-x=0; with x equaling the amount descended or -32.
Step-by-step explanation:
2 (x-3)-4 (x+3)
