This week we learned about application of rational equations.
The key for this part :
First : Read the problem slowly and carefully what is being asked.
Second : Introduce a variable to represent an unknown number
Third : Write an equation the questions gave then solve
And the last one : Write anser in sentence with the unit (km/h,cm..)
Note : less than, up stream (-), greater than or added, down stream (+)
Let’s start with example to know more about it :
Myra takes 2 hours to plant 450 flower bulbs. Francis takes 3 hours to plant 525 flower bulbs. Working together, how long should it take them to plant 1500 bulbs?
