If you can paint 12 magnets in 4 hours how many can u paint in 2 hours and 10 hours?

4 hours = 12 magnets

Convert 4 hours to mins:
4 hours = 240 mins

240 mins = 12 magnets

Divide by 240 on both sides:
1 min = 0.05 magnets

Find 2 hours 10 mins in mins;
2 hours 10 mins = 130 mins

Find number of magnets in 130 mins
1 min = 0.05 magnets
130 mins = 0.05 x 130 = 6.5 magnets

You can paint 6 complete magnets in 2 hours 10 mins
