Answer:4 minutes

Step-by-step explanation:Let the time taken for them to have the same number of strawberries be x minutes.

InitiallyRuby: 10 strawberries

Sapphire: 30 strawberries

After x minutesRuby: (10 +3x) strawberries

Sapphire: (30 -2x) strawberries

Since we let x minutes be the amount of time that has passed when they have the same amount of strawberries,

10 +3x= 30 -2x

Bring all x terms to one side, constant to the other:

3x +2x= 30 -10

Simplify:

5x= 20

Divide both sides by 5:

x= 20 ÷5

x= 4

∴ It will take

4 minutes.
