Mr. Max and Mr. Min start off in the same place and head in opposite directions. Mr. Max is traveling at 60 mph and Mr. Min at 55 mph. How long will it be before the two are 345 miles apart?

it will take 3 hours before the two are 345 miles apart.

Step-by-step explanation:

Let t represent the time it will take for them to be 345 miles apart. It means that after t hours, they would have covered 345 miles.

Distance = speed × time

Mr. Max is traveling at 60 mph. This means that the distance travelled by Mr Max in t hours is 60t

Mr. Min is traveling at 55 mph. This means that the distance travelled by Mr Min in t hours is 55t.

Since the total distance covered is 345 miles, it means that

60t + 55t = 345

115t = 345

t = 345/115

t = 3

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

5/20 so 25%
