Question: Charlie can make 5350 steps while running on a 3-kilometer running field. If he can run around the field 2 1/2 times during a running session, how many steps was he able to make?
Answer: Charlie's steps for 3 kilometers is 5350 x 2 = 10700 steps were made when he run twice the field. Since he has run half of the field 5350 / 2 = 2675 steps were made when he runs half of the 3 - kilometer field. Therefore, Charlie was able to make 10700 + 2675 = 13375 steps for the 2 and a half run around the field. The answer is 13375.
[Question]There are 50 oysters on the rocks at La Push Park and 72 crabs by the beach. Eric, who loves walking by the beach, makes a note of this and goes home. The next day, he realizes only half the number of Oysters were on the rocks, and only 2/3 the number of crabs as the previous day are on the beach. How many oysters and crabs did he count in total in the two days?
[Answer]The first day he saw 50 oysters + 72 crabs = 122 animals. On the second day, he saw 1 / 2 * 50 oysters = 25 oysters. The number of crabs by the beach on the second day was 2 / 3 * 72 crabs = 48. He saw 48 crabs + 25 oysters = 73 animals on the second day. The total for the two days is 73 animals + 122 animals = 195 animals. The answer is 195.
