Answer:

1. 132 km

2. 16 days

3. 4 days

4. 11.14 gasoline

Step-by-step explanation:

1.  99/9 = 11

   9 + 3 = 12 liters

   99 + 33 = 132 km

there are 11 km per liters of gasoline, so i add 11 until it reach the 12 liters of gasoline

2. 6 x 2 = 12 is the number of girls that can work in 8 days

   12/2 = 6 is the number of girls that can work in n

   8 days x 2 = 16 days

i multiply 8 twice since the number of girls that can work in 8 days which is 12 is divided by 2 or twice which resulted into 6 girls then i multiply 8 by 2 or twice which resulted into 16 days

3. 8/2 = 4 days

i divided 8 by 2 since there are two more men that is being added

4. 78/7 = 11.14 gasoline

i divided 78 by 7 since there are 7 gallons of gasoline in 45 miles, i divided 78 by 7 to able to get the number of gasoline that will be use in 78 miles

hope it helps
