Answer: -5 and 5
Step-by-step explanation:
-5 plus 5 added has a sum of 0
Distance = rate * time
trip there, 120 = 55 *t
t = 2 and 2/11 hours
trip back, 120 = r * (2.75 - 2.181818181) round trip time - time to get there
120 = r * .568181818181818
r = 211.2 miles per hour
thinking maybe you did not copy the problem accurately...thats pretty fast.
Note that both 12 and 30 are multiples of 2. Divide the numerator and denominator by 2. 6/15. Note that 6 and 15 are multiples of 3. Divide the numerator and denominator by 3. 2/5. Note that 2 and 5 are both prime numbers. Your answer is 2/5.
Answer:
The next three terms are 55,89 and 144
Step-by-step explanation:
We want to predict the next three numbers in the pattern
3, 5, 8 , 13 , 21 , 34
The difference between two successive terms is written between them.
Thus, we have
3 2 5 3 8 5 13 8 21 13 34
So the rule here is to add the next term to the previous so as to get the next coming term
Thus, we have;
34 + 21 = 55
55 + 34 = 89
89 + 55 = 144
Say the first 3 were 60 seconds and the other 2 were 70 seconds
that comes to 180 sec. and 140 sec. 180+140=320
320 seconds
