Answer:

The real-life distance to the nearest mile between Tampa and Orlando is 88 miles

Step-by-step explanation:

String distance between Fort Myers and Miami = 7 inches

A real life distance between Fort Myers and Miami = 154 miles

So, 7 inches = 154 miles

$1 inch = \frac{154}{7}=22 miles$

Scale : 1 inch = 22 miles

String distance between Tampa and Orlando = 4 inches

Using scale

The real-life distance to the nearest mile between Tampa and Orlando = $4 \times 22 = 88 miles$

Hence The real-life distance to the nearest mile between Tampa and Orlando is 88 miles
