I'm not sure what the question is, but I
assume you want to know Jill's speed
+d+=+r%2At+
+r+=+d%2Ft+
+r+=+%28+8+%2B+3%2F4+%29+%2F+%28+3+%2B+1%2F2+%29+
( note that 3 hrs 30 min = 3 + 1/2 hrs )
+r+=+%2835%2F4%29+%2F+%28+7%2F2+%29+
+r+=+%2835%2F4%29+%2F+%2814%2F4%29+
+r+=+35%2F14+
+r+=+5%2F2+
+r+=+2+%2B+1%2F2+
Jill's speed is 2 and 1/2 units/hr
( miles/hr ? You didn't say what units for distance )
