EIGRP Matrix Formula
metric = [K1 * bandwidth+(K2 * bandwidth)/(256 - load)+K3 * delay] * [K5/(reliability + K4)]
Eigrp matrix weight K1=1,K2=0,K3=1,K4=0,K5=0.
Metric = bandwidth + delay
The lest Metric Formula for Cisco's Router,
Metric={(10,000,000/slowest bandwidth in kbps)+(total delay in microsecond /10)}*256
Slowest bandwidth in kbps=Only one interface's bandwidth that have lowest bandwidth among all outgoing interfaces to desire remote
Total delay in microsecond=The sum of the all outgoing interface's delay.

Sophia's f0/0 has lowest bandwidth,
Metric={(10,000,000/slowest bandwidth in kbps)+(total delay in microsecond /10)}*256
Metric={(10,000,000/10000)+(1100 /10)}*256
Metric={1000+110}*256
Metric={1110}*256 = 284160
Metric={(10,000,000/slowest bandwidth in kbps)+(total delay in microsecond /10)}*256
Metric={(10,000,000/10000)+(6100 /10)}*256
Metric={(1000)+(610)}*256
Metric=(1610)*256 =412160
