1 - If a train is traveling at 90 miles per hour, how many feet is it traveling per second?
Find how many feet in 1 hr, then find how many in 1 sec
{{{90*5280)/3600}}} = 132 ft/sec
:
2 - cameron white traveled 325 miles in 6 1/4 hours.
 what was his average speed per hour?
You should know that speed = dist/time
s = {{{325/6.25}}}
:
3 - a pole that is 9 feet tall casts a shadow that is 6 feet long. at the same time a tree casts a shodow that is 20 feet long. how tall is the tree?
Use the relationship of sides of similar triangles
let = height of the tree
{{{t/9}}} = {{{20/6}}}
Cross multiply, find t
