so find rate rate=degress in x minutes rate=140 in 70 minutes ratiosis 140 to 70 if you wanted to find degrees per minute so you could multiply then do degreees/1 minute=140/70=14/7=2/1=2 degrees per minute 28 minute times 2 degrees per minute=56 degrees
another way is 140/70=xdegrees/28 solve for x multipl yboth sies by 28 and simplify 3920/70=x=56 answer is 56 degrees
