So you know each french fry equals 25 calories. So amount of calories per french fry = 25f
Similarly we know each chicken wing has 100 calories so amount per chicken wing = 100c
So total calories = 25f+100c
Now we know that we want the total to be less than 500
Therefore the inequality should look like this
25f+100c<500
So car A travels Distance = 60 km/hr*(1+x)
Car B travels Distance = 75 km/hr(x)
Where x is the time in hours.
Those two equations are equal when on overtakes the other
so:
60 +60x = 75x
60=15x
x=4, but my expression is written to count from when car B commenced travel. So total time is 5 hours from the car A setting off.
They are 2015 and 2016.
divide 4031 by 2, and get rid of the decimal:
You will get 2015.
2015+2015 = 4030
2015+2016=4031
