Step 1: Convert both time values into improper fractions.9 1/2 = 19/21 1/4 = 5/4Step 2: Divide total time by the interval time:19/2 ÷ 5/4 = 19/ 2 × 4/5 = 76/10 = 7.6Step 3: They stopped 7 full times.The 0.6 means they were near another stop, but they didn’t complete another full interval.They stopped to rest 7 times during the tour.
