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
