Calculate like in class

Lernheft calculates the way your teacher expects – with the methods, formulas and grades of your country. Here, for example, as at a German school: rearrangements with the calculation step beside them, Given – Find – Solution and a sentence answer at the end.

  1. 3x+3=273x + 3 = 27−3-3
  2. 3x=243x = 24:3:3
  3. x=8x = 8

A cyclist covers 120 m in 8 s. How fast is he going?

Given
s=120 m;  t=8 ss = 120\,\text{m};\; t = 8\,\text{s}
Find
vv
Solution
v=st=120 m8 sv = \dfrac{s}{t} = \dfrac{120\,\text{m}}{8\,\text{s}}
v=15 msv = 15\,\tfrac{\text{m}}{\text{s}}

Answer: The cyclist travels at 15 m/s.
