If the CAT operates with a constant speed of 53 mph (which means it beats 53 miles in one hour) and makes a trip in about 2 and 1/2 hours, we just have to multiply 53 by 2 1/2 to find out the overall distance it's beating in that time:
53 * 2 1/2 = = 53 * 2.5 = = 132.5
Answer: City A is about <u>132.5 miles</u> from city B.
