D=vt+(v+12)t
d=vt+vt+12t
d=2vt+12t
d=2t(v+6), and we are told that d=232 and t=2
2(2)(v+6)=232
4(v+6)=232
v+6=58
v=52
So the slower car is travelling at 52 mph and the faster car is traveling at 64 mph.
Answer:
-4 and -3.
Step-by-step explanation:
Let the numbers be x and x+1.
From the given information:
x^2 + (x + 1)^2 + x = 21
x^2 + x^2 + 2x + 1 + x - 21 = 0
2x^2 + 3x - 20 = 0
(2x - 5 )(x + 4 ) = 0
x = 5/2 or -4 We ignore 5/2 as its not an interger
So the required integers are -4 and -3.
Answer:
2380.13195
Step-by-step explanation:
2193.67÷200=10.96835
