Answer this question:Javier is an Olympic javelin thrower. In the last Olympics, he threw the javelin three times. The first throw, he threw the javelin twice as far as he threw the javelin on his second throw, but only half as far as he threw it the third throw. If the sum of all three throws was 1050 meters, then how far, in meters, did he throw the javelin on his first throw?
Let x be the distance he threw the javelin on the first throw. Thus, the sum of his three throws is x + 0.5x + 2x = 1050 meters. Thus, 3.5x = 1050. And we find the distance he threw the javelin on the first throw is x = 300 meters.
The answer is 300.

Answer this question:A dog barks 30 times per minute. If 2 dogs bark 30 times per minute, how many times will they have barked after 10 minutes?
There are 2 dogs and they each bark 30 times per minute so together they bark 2 * 30 = 60 times per minute. 2 dogs bark a combined total of 60 times per minutes, after 10 minutes they will have barked 60 * 10 = 600 times.
The answer is 600.

Answer this question:The file, 90 megabytes in size, downloads at the rate of 5 megabytes per second for its first 60 megabytes, and then 10 megabytes per second thereafter. How long, in seconds, does it take to download entirely?
The first 60 megabytes take 60 / 5 = 12 seconds. There are 90 - 60 = 30 remaining megabytes. The remaining 30 megabytes take 30 / 10 = 3 seconds. And 12 + 3 = 15 seconds.
The answer is 15.
