Question

Sakura speaks 150 words per minute on average in Hungarian and 190 words per minute on average in polish she once gave cooking instructions in polish Sakura spent 5 minutes total giving both instructions and spoke 370 more words in polish than Hungarian

Answer 1

let p time in minutes speaking Polish
let h time in minutes speaking Hungarian

p + h = 5 equation 1

190 p - 150 h = 370 equation 2

multiply eq. (1) by 150 (both sides)

15 0p + 150 h = 750

190p -150 h = 370

add the two eqiations we get :

190 p + 150p = 370 + 750

340 p = 1120

p= 1120/ 340 = 3.29

3 minutes speaking Polish and 2 minutes speaking Hungarian.


make sure if the number 370 ?? i think it is wrong , it can be 270 because i get a point in the answer
