Brandon is preparing for a weightlifting competition. To qualify for the final, he needs to be able to lift at least 417 kg. Brandon is able to lift 197 kg comfortably now. Each month, he is able to increase the mass he lifts by 10 kg. How long must Brandon train to qualify for the final? Give your answer in years and months. (Eg 2 years 3 months)
Remaining mass that Brandon needs to be able to lift
= 417 - 197
= 220 kg

Number of months that Brandon must train to be able to lift the extra 220 kg 
= 220 ÷ 10
= 22 months

1 year = 12 months
22 ÷ 12 = 1 r 10

Duration that Brandon must train to qualify for the final = 1 years 10 months

Answer(s): 1 years 10 months
