Answer:
210 kilometers
Step-by-step explanation:
<em><u>First; we are going to divide.</u></em>
60(hour in minutes) / 20 mins ...to find out what the excess distance the car went.
Which is 1/3 or 0.3333333...
<u><em>Second; we are going to combine the decimal and the whole number together.</em></u>
2 hours + 0.333333... hours = 2.3333333...hours
<u><em>Finally; we are going to multiply</em></u>
90 (km/h) * 2.33333333
Which equals ...210 kilometers!!
Firstly let’s make the -2 2/3 easier
-2*2/3= -4/3
Then we will move all the numbers to one side and keep the x on the other side. Remember when u move a negative from one side of the equal sign it changes to positive and if u move a positive it changes to a negative.
X= -4/3+15-7
=-4/3+8
=-4/3+24/3 (To add fractions the denominator has to be the same, and 24/3 is the same as 8)
X=20/3
Hopefully this helps
