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
