Answer

A speed skater \( \nabla \) travels \( 26 - 12.5 = 13.5 \) meters per second faster than a cheetah.

Steps

Step 1 ：A speed skater travels \( 12.5 \) meters per second.

Step 2 ：A cheetah travels \( 26 \) meters per second.

Step 3 ：A speed skater \( \nabla \) travels \( 26 - 12.5 = 13.5 \) meters per second faster than a cheetah.
