Answer:
10 miles per minute
Step-by-step explanation:
distance = speed x time
but we are working out the speed, so it is speed = distance/ time
it takes 12 minutes, so we do 120/ 12 which gives us 10
2×2 +11x - 6 =0
4 + 11x - 6 = 0
11x - 6 =4
-6 + 4 = 11x
-2 = 11x
X =11/2
X =5.2
Answer: Decrease
Figure: Amount of tiles:
1 5
2 8
3 11
4 14
5 17
6 20
7 23
8 26
9 29
10 32
11 35
12 38
13 41
The sequence/pattern is +3 tiles.
So Figure 13 will have 41 tiles.
I hope this helps!
