Ответ:
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
