It took 32 minutes for Ella to go to school on Friday.

Step-by-step explanation:

Time for first four days in minutes,

30,28,34,31

Let x be the time on Friday

Average = 31 min

As we know

$Average = \frac{Sum\ of\ term}{No.\ of\ terms}\\Average=\frac{30+28+34+31+x}{5}\\31=\frac{123+x}{5}$

Multiplying both sides by 5;

$5*31=\frac{123+x}{5}*5\\155=123+x\\x+123=155\\x=155-123\\x=32$

It took 32 minutes for Ella to go to school on Friday.
