Answer 2

Answer:

A. $\frac{170}{100}m$

B. $1.7m$

Step-by-step explanation:

Given,

The average wait time at the hospital was m minutes,

And, after outbreak it is increased by 70 %,

Thus, the average wait time at the hospital after the outbreak = The average wait time before outbreak + 70 % of the average wait time before outbreak

$=m+\frac{70m}{100}$

$=\frac{100m+70m}{100}$

$=\frac{170m}{100}$

$=1.7m$

Hence, Option A and B are correct.
