Answer:
Option (b): 10 cars
Step-by-step explanation:
We have the following numbers:
55, 86, 2, 12, 72 and 48
First we order them from least to greatest according to the intervals shown in the fourth column of the table.
So, we have
2, 12
48, 55
72, 86
The first two numbers (2, 12) enter the first interval (1-18) corresponding to the arrival of 0 cars
The third and fourth number (48, 55) enters the third interval (41-70) that corresponds to the arrival of 2 cars.
The fifth and sixth numbers (72, 86) enter the fourth interval (71-87) that corresponds to 3 cars.
So we have that, according to the numbers given, the number of cars arriving in an hour is:
0 + 0 + 2+ 2 + 3 + 3 = 10 cars
The correct answer is the option (b) 10 cars
