April: 13.5+8.7+11.1
March: (13.5+8.7+11.1)÷2
May: 4×(13.5+8.7+11.1)
April: 33.3
March: 33.3÷2=16.65
May: 4×33.3=133.2
Proportion: 133.2÷16.65=8
so 133.2:16.65 is equal to 1:8. So she rode 8 times Farther in May then in March.
The month that she rode the most is May the least is March. If you want me to do step by step on the addition I will.
The answer is 18,800 g
16kg is the same as 16,000g Then add that to 2,800g
10.1666666667
Hope it helps
