It takes mrs. hughes 60 minutes to correct 15 math tests. how long would it take her to correct 60 math tests?

60 ÷ 15 = 4

4 minute per math test

4 × 60 = 240

240 minutes to correct 60 math tests =)

Use ration format 60:15, x:60 cross multiply and you will get 3600=15x. Divide both sides by 15 and x=240

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
