The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

    \n
  1. Car’s Average Speed:<\/strong><\/li>\n<\/ol>\n\n\n\n

    The formula for average speed is: Average Speed=Total DistanceTotal Time\\text{Average Speed} = \\frac{\\text{Total Distance}}{\\text{Total Time}}Average Speed=Total TimeTotal Distance\u200b<\/p>\n\n\n\n

    Given that the car travels 150 kilometers in 3 hours, the average speed can be calculated as: Average Speed=150 km3 hours=50 km\/h\\text{Average Speed} = \\frac{150 \\text{ km}}{3 \\text{ hours}} = 50 \\text{ km\/h}Average Speed=3 hours150 km\u200b=50 km\/h<\/p>\n\n\n\n

    Thus, the correct answer is A. 50 kph<\/strong>.<\/p>\n\n\n\n

    \n\n\n\n
      \n
    1. Bus Distance Traveled:<\/strong><\/li>\n<\/ol>\n\n\n\n

      To calculate the distance traveled by the bus, we use the formula for distance: Distance=Speed\u00d7Time\\text{Distance} = \\text{Speed} \\times \\text{Time}Distance=Speed\u00d7Time<\/p>\n\n\n\n

      Given that the bus travels for 7 hours at an average speed of 82 km\/h, we can calculate the distance: Distance=82 km\/h\u00d77 hours=574 km\\text{Distance} = 82 \\text{ km\/h} \\times 7 \\text{ hours} = 574 \\text{ km}Distance=82 km\/h\u00d77 hours=574 km<\/p>\n\n\n\n

      Thus, the correct answer is C. 574 km<\/strong>.<\/p>\n\n\n\n

        \n
      1. Ben\u2019s Average Speed:<\/strong><\/li>\n<\/ol>\n\n\n\n

        To find Ben\u2019s average speed for the entire trip, we need to first calculate the total distance traveled and the total time taken.<\/p>\n\n\n\n

          \n
        • Total Distance:<\/strong><\/li>\n<\/ul>\n\n\n\n

          Ben traveled:<\/p>\n\n\n\n

            \n
          • 150 miles in 3 hours<\/li>\n\n\n\n
          • 120 miles in 2 hours<\/li>\n\n\n\n
          • 70 miles in 1 hour<\/li>\n<\/ul>\n\n\n\n

            The total distance is: Total Distance=150+120+70=340 miles\\text{Total Distance} = 150 + 120 + 70 = 340 \\text{ miles}Total Distance=150+120+70=340 miles<\/p>\n\n\n\n

              \n
            • Total Time:<\/strong><\/li>\n<\/ul>\n\n\n\n

              The total time is: Total Time=3 hours+2 hours+1 hour=6 hours\\text{Total Time} = 3 \\text{ hours} + 2 \\text{ hours} + 1 \\text{ hour} = 6 \\text{ hours}Total Time=3 hours+2 hours+1 hour=6 hours<\/p>\n\n\n\n

              Now, we calculate the average speed: Average Speed=340 miles6 hours=56.67 mph\\text{Average Speed} = \\frac{340 \\text{ miles}}{6 \\text{ hours}} = 56.67 \\text{ mph}Average Speed=6 hours340 miles\u200b=56.67 mph<\/p>\n\n\n\n

              Thus, the correct answer is A. 56.67 mph<\/strong>.<\/p>\n\n\n\n

              \n\n\n\n

              These types of questions are all based on fundamental concepts in motion and speed calculations, where it’s crucial to know how to apply basic formulas for speed, distance, and time.<\/p>\n\n\n\n
