After robbing a bank in Dodge City, a robber gallops off at 13 miles/hour. 30 minutes later, the marshall leaves to pursue the robber at 15 miles/hour. How many hours does it take the marshall to catch up to the robber?

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.

except if the answer is in the value of money, then, it will matter. it will have to be $0.40, but i can tell this is not a money question, so .4 should be the right one.
