Question

一台计算机每秒可以做 $10{,}000$ 次加法。它一小时可以做多少次加法？

A computer can do $10{,}000$ additions per second. How many additions can it do in one hour?

$6$ 百万

$6$ million

$36$ 百万

$36$ million

$60$ 百万

$60$ million

$216$ 百万

$216$ million

$360$ 百万

$360$ million

一小时有 $3600$ 秒，所以计算机可以做 $10{,}000 \times 3600 = 36{,}000{,}000$ 次加法。

也就是 $36$ 百万。

所以正确答案是 B。

One hour has $3600$ seconds, so the computer does $10{,}000 \times 3600 = 36{,}000{,}000$ additions.

That is $36$ million.

Thus, the correct answer is B .
