某计算机接收信息的速度为每秒2.8千字节;发送信息的速度为每秒3.8千字节。现在要从A处接收,往B处发送,还要将机内储存的58千字节的信息也发送至召处.如果发送接收轮流进行,每次发与收各10秒.问: 1)若先发送,经过多少秒恰好将机内储存的信息送完? 2)若先接收,经过多少秒恰好将机内储存的信息送完?(答案保留
The speed at which a computer receives information is 2.8 kilobytes per second; the rate at which information is sent is 3.8 kilobytes per second. Now we need to receive from A and send it to B. We also need to send 58 kilobytes of information stored in the machine to the call. If the sending and receiving are done in turn, each sending and receiving will take 10 seconds each time. Q: 1) If it is sent first, how many seconds will exactly send the information stored in the machine? 2) If it is received first, how many seconds will be used to send the stored information?
