a= min/wk spent on aerobics
w= min/wk spent on weight training
a+%2B+w+=+250 min/wk
a%2Fw+=+3%2F2
a+=+%283%2F2%29%2Aw
%283%2F2%29%2Aw+%2B+w+=+250
%285%2F2%29%2Aw+=+250
5w+=+500
w+=+100 min/wk
w+=+100%2F60 hrs/wk
w+=+1hr,40min
a+=+%283%2F2%29%2A100
a+=+150 min/wk
Kay spends 150 min/wk on aerobics and (1 hr 40 min)/wk on weight training
