Question

Sherman wants to drive to a restaurant during a 60-minute lunch break. He will spend 40 minutes at the restaurant. How long can the one-way drive to the restaurant be, if driving each way (there and back) takes the same time?

Answer 1

Sherman has 20 minutes available for travel during his 60-minute lunch break, after spending 40 minutes at the restaurant. Thus, he can spend up to 10 minutes on a one-way drive to the restaurant.

Step-by-step explanation:

Sherman wants to make the most of his 60-minute lunch break, planning to spend 40 minutes at the restaurant. The remaining time must account for the round trip travel to and from the restaurant. Therefore, the calculation for the maximum one-way driving time is as follows:

• Total lunch break time: 60 minutes
• Total time at the restaurant: 40 minutes
• Total available travel time: 60 minutes - 40 minutes = 20 minutes
• One-way drive time: 20 minutes total travel time / 2 = 10 minutes

Hence, Sherman can spend a maximum of 10 minutes driving each way to the restaurant.
