Their speed of separation will be equal to the sum of their speeds because they are in opposite directions.
Speed of separation = 40 + 50 = 90 miles per hour

Time = distance / speed
Time = 405 / 90
Time = 4.5 hours

In a certain card game, for every 44 blue cards, there are 33 yellow cards. There are a total of 84 blue and yellow cards in the
worty [1.4K]
Use a proportion.

A ratio of 44 blue to 33 yellow is the same as a ratio of 4 blue to 3 yellow.

Since you are told the total of cards, 84, add 3 + 4 = 7

In the deck, the cards are int he ratio of 4 blue to 3 yellow to 7 total.

4 blue to 7 total = x blue to 84 total

4/7 = x/84

7x = 4 * 84

x = 4 * 12

x = 48

There are 48 blue cards.
