Answer:
A) d = 48t, d in miles, t in hours
B)d = 32t, d in miles, t in hours
C)y = 8 mph
Step-by-step explanation:
16 miles in 20 mins = 48 mph
16 miles in 30 mins = 32 mph
The boat speed is the average = (48 + 32)/2 = 40 mph
The current is the difference = 8 mph
Answer: 320 g
Step-by-step explanation:
We can set up a ratio.
Let the amount of oats equal to x.
18/240 = 24/x
We can now cross multiply.
18x = 5760.
x = 320 g
32000 and 500 , so the number 32000 has three 0 and 500 2 , so you can take off two 0 from 32000, which equals to 320 .You have to find a number that times 5 equals 320 or almost , the most approaching number is 6 , because 5 times 6 equals 30 , then you have to subtract, the result of the subtraction is 2 , 2 is less than 5 so we have to put a zero , so we got 20 , which number times 5 can give you 20 ? , 4 , so your answer is 64 .
There are 16 cups in a gallon. Divide 100 into 16 to get 6.25. You now just multiply 3.12 by 6.25 to get 19.5. Your answer is $19.50.
hope this helps!
