If each blue tile has 5 sides and you know you have 3 blue tiles you can multiply 5 by 3
5 x 3 = 15 sides
Next you know the total number of sides is 30 and you just figured out that your 3 blue tiles have a total of 15 sides so you can subtract 15 from 30 to find how many sides are left
30 - 15 = 15sides
Since you know that these are not blue tiles because in the question it stated that you have 3 blue tiles. These have to be sides for red tiles.
Each red tile have 3 sides so you can divide 15 by 3
15/3 = 5
There are 5 red tiles
You are the number 5
X equals 2. 2 times 2 equals 4, then you multiply it by 2 again, which equals 8. Basically you just have to find the square root of 8, which is 2.
Add the two trips together for total Km’s:
4500 + 11700 = 16,200 km.
divide total km by speed:
16,200 / 1,100 = 14.727272 hours
0.727272 x 60 minutes per hour = 43.636363 minutes, round up to 44 minutes
total time: 14 hours and 44 minutes
