(20,15- 1,638:4,2)+0,125*80

Слайд 7Ok. Now, please, check your answers.

Слайд 8Soon Prince Ivan reached the wide river where there was neither

bridge nor boat.

Suddenly the heavy wave cast Goldenfish ashore . It said with a human voice:”This river will disappear if you solve a mathematical problem correctly” .

Слайд 9Task № 2
Once the witch Baba-Yaga and Kashchei the

Immortal flew out towards each other simultaneously . There were about 650 km between Baba Yaga’s hut on chicken legs and Kashchei’s castle. The Baba Yaga’s speed was 50.6 km per hour. In 5.2 hours they met on the forest edge . Please, find out Kashchei’s speed.

Task № 2 Once the witch Baba-Yaga and Kashchei the Immortal flew out towards each other

Слайд 10Please, look at this scheme
50.6 km per hour

5,2 h

? km ? km

650 km

Please, look at this scheme50.6 km per hour 5,2 h

Слайд 11Rational Calculation
1) 650:5,2= 125(km per hour)- the closing speed ;
2)

125-50,6=74,4(km per hour)
Ответ: Kashchei’s speed is 74,4 km per hour.

Rational Calculation 1) 650:5,2= 125(km per hour)- the closing speed ;2) 125-50,6=74,4(km per hour) Ответ: Kashchei’s speed

Слайд 12Please, look at another possible way of doing the task (

using equation)

Let Kashchei’s speed equal X. So the closing speed will equal(50,6 + x) km per hour and their travel will be 5,2(50,6+X) km. But we know that their travel in accordance with the task equals 650 км.
Please, equate:
5,2(50,6+X)=650
