Ashley's teacher asked her to bring 3 pieces of yarn, each no shorter than 0.8 m, for an art project. Ashley found a piece of old yarn at home that is 280 cm long. Does she have enough yarn to bring to school?

230 erasers = 230 x 17 mm =3910 mm = 3.910 m ( 1 m = 1000 mm)

Difference in time from 7 : 15 pm to 10 : 45 pm = 3 hr 30 mins.=3:30
Length of 1 yarn = 0.8 m
Length of 3 yarns = 3 x 0.8 = 2.4 m= 240 cm ( 1 m = 100 cm)
Ashley has 280 cm of yarn, which is more than 240 cm . hence, she does have enough yarn to bring to school.
