A cannot be the answer.
The maximum distance he can travel is 420 miles. He has gone 180. He still has 420 - 180 = 240 miles left to go.

C The distance is correct in the first set of brackets, but you cannot add distance divided by time (which is a speed) to distance.

D is incorrect. The first set of brackets is correct, but the second set is meaningless. Distances and rates do not mix.

B <<<<< Answer If you divide the remaining distance (240) by the rate (180/3) you get the correct answer of 4 hours.

B <<<< answer.

I need help on question 4 and 10
nevsk [136]

The equivalent sets are <u>X n Y = { } and X U Y= {5, 6, 7,8, 9, 10, 12 ,14}</u>

<h3>Set theory and notation</h3>

Given the following sets expressed as;

X = {8, 10, 12, 14}

Y = {5, 6, 7, 8,9}

Since union means the combination of all the elements in both sets and intersection is the common elements in the set, hence;

X n Y = { }

X U Y= {5, 6, 7,8, 9, 10, 12 ,14}

Note that the intersection is an empty set since there is no common element
