Fred can run 12 miles in 1 hour and can bike 30 miles in 2 hours. What percent of Fred’s average biking speed is his average run

S_A_V [24]

first thing you have to do is find the rate for the bike so you divide 30 by 2 and you get 15 after you do that you make a problem to find the percentage so you take x/100 and 12/15 then you take 12 times 100 and that gives you 1200 then you divide by 15 and get 80. So the answer is 80%

Max tossed a fair coin 3 times. What is the probability of getting heads in the first two trials and tails in the last trial?

sasho [114]

3 over 8 each flip has the same probability of head and tails (1/2) since there are only two sides. He flipped it three times which means there were 3 chances of the coin to land on either side.
