    Answer:

    51 miles/hour

    Explanation:

    Talia is on a road trip with some friends. in the first 2 hours, they travel 100 miles. then they hit traffic and go only 30 miles in the next hour. the last hour of their trip, they drive 75 miles. calculate the average speed of talia’s car during the trip. give your answer to the nearest whole number.

    The average speed would be 51 miles/hour.

    The average speed of a moving object is defined as the total distance traveled relative to the total time taken fro the journey. Mathematically, it is given as:

      total distance traveled/total time taken.

    In this case;

    Total distance traveled = 100 + 30 + 75 = 205 miles

    Total time taken = 2 + 1 + 1 = 4 hours

    Therefore;

    Average speed = 205/4 = 51.25 miles/hour

    To the nearest whole number = 51 miles/hour
