Question

Find the difference between the fastest girls time and the slowest girl time. Barbra ran 3 3/10, Donna ran 2 4/5 , Cindy ran 4 3/5 and Nicole ran 2 1/10

Answer 1

Answer:4/5 minute

Step-by-step explanation:Fastest girl time = 21/10 Slowest girl time = 34/10 difference = (34-21)/10 = 13/10 (3) Total time = 33/10 + 28/10 + 34/10 + 21/10 = 116/10 Previous record = 12 2/5 = 62/5 = 124/10 As the time taken by girls (116/10) is lower than the previous record (124/10) Therefore these girls are faster by (124-116)/10 = 8/10 minutes = 4/5 minutes
