Using 2:7 and 3:2, the LCM is 45 The total number of pages = 45 units. On Monday - Read vs unread 18 vs 35 On Tuesday - Read vs unread 27 vs 18 This means he read 27-18 units on Tuesday = 9 units. On Wednesday, he finished the book, meaning he finished the 18 units that were incompleted from Tuesday. Since he read 18 units on Wed and 9 units on Tuesday, 57 pages = 18-9 = 9units. ==> 45 units = 57*5=285

2:7 means 9 units. 3:2 means 5 units. I want the units to be the same for both. So find the LCM. What is the lowest number of units I require so that I can have the same unit Base? I used 9x5

Total distance: 10T1 = 8T2 5T1 = 4T2 --- equation 1 T1 + T2 = 6/5 5T1 + 5T2 = 6 --- equation 2 Substitute 1 into 2. 4T2 + 5T2 = 6 1T2 = 6/9 h = 2/3 h = 40min. T1 -> home to park T2 -> park to home
