Answer:
B
Step-by-step explanation:
To solve this, we use ratio.
Firstly, we need to know the number of hours traveled. The total number of hours traveled = x+y
Ratio of this used by high speed train = x/(x +y).
Total distance traveled before they meet = [x/(x + y)] × z
For low speed train = [y/(x + y)] × z.
The difference would be distance by high speed train - distance by low speed train.
= z [ (x - y)/x + y)]
Answer:
The correct answer is:
New students laughing at Steve
10 × 10 = 100
Add all the students laughing at Steve
10 + 100 = 110
Add Steve
110 + 1 = 111
There were 111 students in total laughing.
