老师，我还是没搞懂为什么借入时间是5个月

NO.PZ2016082402000057 问题如下 A long position in a 2 x 5 FRA is equivalent to the following positions in the spot market: Borrowing in two months to finana five-month investment Borrowing in five months to finana two-month investment Borrowing half a loamount two months anthe remainr five months Borrowing in two months to finana three-month investment ANSWER: BFRA finet1×t2t_1\times t_2t1​×t2​ involves a forwarrate starting time t1t_1t1​ anenng time t2t_2t2​ The buyer of this FRA locks in a borrowing rate for months 3 to 5. This is equivalent to borrowing for five months anreinvesting the fun for the first two months. 画红线那句话根本没看懂，为什么borrow是5个月 ，loan实际只有3个月啊，还有投资是什么意思，前面的2个月是投资？？？
