Question

Maria exercises for 2 1/7 hours every Saturday. She runs for 1/3 of the time that she exercises. How much time does she spend running every Saturday?

Answer 1

`2(1)/(7)*(1)/(3)=(15)/(7)*(1)/(3)=(15*1)/(7*3)=(15)/(21)=(5)/(7)`

`(5)/(7)*60=(5*60)/(7)=(350)/(7)=42,(857142)min\approx 42.86min`
