Sam and Liam raced each other up and then down the hill. Sam's average speed up the hill was 1 mph, and his average speed down the hill was 9 mph. Liam ran up the hill with the same speed, 2 mph. If the path from the bottom to the top of the hill was 1 mile long, how much time did it take each of the boys to finish - and who was the winner?

So, Liam took one hour and Sam took 1 and 1/9 hours, in conclusion liam was faster

Step-by-step explanation: sorry I only know the answer

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%
