Question

На автогонках скорость тойоты составила 0,7 скорости Феррари.Найдите скорость Феррари,если скорость тойоты на 57км.ч. меньше скорости Феррари ?

Answer 1

1)1-0,7=0,3 разница в скоростях. 2) 57:0,3=190(км/ч) скорость Феррари.

Answer 2

Calculation of Ferrari's Speed

To find the speed of the Ferrari, we are given that the speed of the Toyota is 0.7 times the speed of the Ferrari, and the speed of the Toyota is 57 km/h less than the speed of the Ferrari.

Let's denote the speed of the Ferrari as x km/h. According to the given information, the speed of the Toyota is 0.7 times the speed of the Ferrari, which can be expressed as:

0.7x = x - 57

To solve this equation, we can isolate x by subtracting 0.7x from both sides:

0.3x = 57

Then, we can solve for x by dividing both sides by 0.3:

x = 57 / 0.3

Now, let's calculate the value of x:

x = 190 km/h

Therefore, the speed of the Ferrari is 190 km/h.
