Tyrone almost forgot that he promised to pick up a prescription for his mother at the drug store across town. His mother is due home in 45 minutes. If Tyrone is able to make the 12.5 mile trip to the store and back again before his mother gets home, can he obey the posted speed limit of 35 mph?

The limit is 35 miles per hour. Tyrone has 45 minutes, which is three quarters of an hour. So, the most that he can travel is threequarters of 35. 3/4 * 35 = 26.25 The journey is 12.5 miles. It's not too clear from the question whether this means it's 12.5 miles to the store, or 12.5 miles to the store and back. If it's 12.5 miles to the store, then the total journey is 12.5 * 2 = 25 Since 25 is less than 26.25, then he can obey the limit, as long as it doesn't take too long to pick up the prescription!
