What is an equation?
An equation is an expression that shows the relationship between two or more variables and numbers.
Sound travels at approximately 1080 feet per second. Hence:
Marsala hears her echo 1.7 seconds later, hence:
Total distance = 1080 * 1.7 = 1836 feet
Depth of canyon = 1836 / 2 = 918 feet
