3( -4 ) = y - 5
-12 = y - 5
y = -7
All of the disks = 100%.
40% are red.
2/5 = 40/100 = 40% are yellow.
40% + 40% = 80%
100% - 80% = 20%
20% of the disks are blue.
20% can also be written as 20/100, which simplifies to 1/5.
1/5 of the disks are blue.

Answer: speed = 22 meters/minute
distance = 500 meters
by using the formula, speed = distance/time,
therefore, time = distance/speed
t = 500/22
t = 22.72 minutes
