Question

Naomi has earned 54 dollars mowing lawns the past two days. She worked 2 1/2 hour yesterday and 4 1/3 hours today. If Naomi is paid the same amount for every hour she works,how much does she earn per hour to mow lawns? Please explain/show work

Answer 1

Ontem = 1/2 h = 0,5 h = 30 min
hoje = 4 h + 1/3 h = 1 h + 60/3 = 1 h e 20 min = 80 min

30 min + 80 min = 110 min

110 min.................54
60 min....................x

11x = 54*6
11x = 324
x = 324/11
x ~ 29,45 por hora
