three, twelve, five, and six
First you do 3 + 4 + 5 = 12, so there are 12 parts to this ratio.
48 / 12 = 4, this means that each part of the ratio is worth 4 inches.
The longest side is worth 5 parts of the ratio.
4 * 5 = 20 inches

Answer:
It will take Winston 11 seconds to hop 44 meters and catch up to Tina
Step-by-step explanation:
Set up an equation where x represents the number of seconds:
Tina will be represented by s + 33 since she goes 1 m/sec and she has a 33 meter head start, and Winston will be 4s. We need to find when Winston will catch up, so we need an equal sign.
s + 33 = 4s
Solve for s:
s + 33 = 4s
33 = 3s
11 = s
= 11 seconds
Then, plug in 11 as s to find how many meters he will go:
s + 33
11 + 33 = 44
= 44 meters

x:45
x = (45/5) x 6
45/5 = 9
9 x 6 = 54
