Answer:

Sara is taller than Michael

Step-by-step explanation:

From the question, Sara tells Michael she is 160 centimeters tall, that is

Sara's height is 160 centimeters.

and Michael says he is 60 inches tall, that is

Michael's height is 60 inches.

To determine who is taller among Sarah and Michael, we will have to compare their heights in the same unit.

Lets compare the heights in centimeters,

Sara's height is in centimeters, then

We will have to convert Michael's height from inches to centimeters

From the question, If there are 2.54 centimeters in an inch, that is

1 inch = 2.54 centimeters

Then 60 inches = 60 × 2.54 centimeters

= 152.4 centimeters

Hence, Michael's height in centimeters is 152.4 centimeters

Since Sara is 160 centimeters tall, then Sara is taller than Michael.
