Question

Leslie and her brother are going to a hockey game on Saturday. The game starts at 7:15 P.M.It takes 1 hour and 15 minutes to drive to the hockey rink, and they want to get there 1 hour and 15 minutes before the game starts to get good seats. What is the latest time Leslie and her friends can leave for the game?

Answer 1

Solution:

Given:

$\begin{gathered} Game\text{ starts by }7:15P.M \\ \\ \\ driving\text{ time}=1hour\text{ 15minutes} \\ They\text{ want to arrive 1hour and 15minutes early before the game starts} \end{gathered}$

This means they need to factor in the driving time and the time to get there before the game starts to know their departure time.

Hence, total time is;

$1hr\text{ 15mins}+1hr\text{ 15mins}=2hrs\text{ 30mins}$

They must leave 2 hours and 30 minutes early before the game starts.

Hence, the latest time Leslie and her friends can leave for the game is;

$\begin{gathered} 7:15P.M-(2hrs\text{ 30mins\rparen} \\ =4:45P.M \end{gathered}$

Therefore, the latest time Leslie and her friends can leave for the game is 4:45P.M
