    Take local speed ad 30 mph and express your answer in miles

    Answer:

    7.5 miles

    Step-by-step explanation:

    Time for lunch is 1 hour but once will wait for 30 minutes before served and eat.

    Out of 1 hour, 30 mins is for service and eating to mean time to get from work to restaurant, to and fro is the other 30 mins

    Since 30 mins is for to and fro, then one way direction takes 15 mins.

    Speed, s=d/t and distance d=speed*time

    Given local speed of 30 mph and time as 15 mins,

    To convert minutes to hours, we divide it by 60 hence the distance is

    30*15/60=7.5 miles

    Therefore, the student can go to a restaurant that is 7.5 miles from the office.
