Порешала я... наконец... Четыре часа, фух!
Баллы вышли странные... и как это оценивать?! Хотя похоже на то, что письмо и грамматика у меня идут лучше, а лексика и математика идут после, вровень. Но кто его знает?
20 минут на полноценное эссе - так мало!
Математика простая, кстати. Иногда выдаётся, конечно, странный тип заданий, но в общем легко. оО"
Американские задачки)))

A car travels a distance of 250 miles, 700 miles and 325 miles at the rate of 50 miles/hr, 35 miles/hr and 13 miles/hr respectively.Find the average speed of the car in miles/hr.
Your answer: 13
Correct answer: 25.5
As other speeds given are not equal to the calculated average speed only option B is correct.

By which of the following number is 98765432 exactly divisible?
Your answer: 11
Correct answer: 8
* Option A is not correct is not correct. 98765432 is not divisible by 9 as the sum of its digits 44 is not divisible by 9.
* Option B is not correct as 98765432 is not divisible by 7.
* Option C is not correct as the last digit of 98765432 is not 5, hence 98765432 is not divisible by 5.
* Option D is correct. Using the tests of divisibility, we know that a number is divisible by 8 if its last three digits are divisible by 8. The last three digits of the given number 432 is divisible by 8.
* Option E is not correct. As the difference of the sum of digits in its even and odd places {(9 + 7 + 5 + 3) - (8 + 6 + 4 + 2)} 4 is not a multiple of 11, 98765432 is not divisible by 11.
