Answer 1

Малыш - 9 мин 

Карлсон - ? в 2 раза быстрее   

За - ? мин съедят варенье и на ? Карлсон съест больше  

 1) 900:9=100(г)-мин съедает Малыш 

2) 100*2=200(г)- съедает Кралсон

3) 100+200=300(г)- вместе за 1 мин

4) 900:300=3(мин)- съедят они все варенье    

3*100=300(г)-варенья съест Малыш

200*3=600(г)-варенья съест Карлсон  

600-300=300(г)

Ответ : 3 мин съедят все варенье , и Карлсон съест на 300 г больше чем Малыш

Problem Analysis

To solve this problem, we need to determine the time it takes for both the child and Karlsson to eat the 900g of raspberry jam and calculate how much more jam Karlsson eats compared to the child. We are given that the child can eat the jam in 9 minutes, and Karlsson is twice as fast as the child.

Solution

Let's start by calculating how long it takes for Karlsson to eat the jam. Since Karlsson is twice as fast as the child, he can eat the jam in half the time. Therefore, Karlsson can eat the jam in 9 minutes / 2 = 4.5 minutes.

Next, we need to calculate how much jam Karlsson eats compared to the child. Since Karlsson eats twice as fast as the child, he eats twice as much jam in the same amount of time. Therefore, Karlsson eats 2 *
