A. White lines separating lanes
Answer:
53.33 hours or 53 hours and 20 minutes.
Explanation:
Given, one travels at 45 miles/hr and another 30 miles/hour.
Let, the slower broom, S1 = 30t
According to the Question,
S1 + 800 = 45t....... (1)
S1 = 45t - 800......(2)
t is constant for because time is equal for both.
Now, putting (1) in equation (2),
30t = 45t - 800
30t - 45t = - 800
15t = 800
t = 53.33
So, the answer is 53.33 hours.
2nd one because it’s I elastic
There are 2 cups in a pint, therefore to find the number of cups in 20 pints you would multiply 20 pints by 2.
20 pints = 40 cups (20 * 2)
There are 4 quarts in a gallon, so to find the number of <em>gallons </em>there are in 29 quarts you would divide 29 quarts by 4.
29 quarts = 7.25 gallons (29/4)
Step 1 is simplify the fraction
step 2 is group all constants on the right side of the inequality
step 3 is isolate the X
