 As a member of FEMA, you’re required to set up a contingency plan to supply meals to residents of a town devastated by a tornado.

Definition
 D. 375 miles The train headed for Wichita traveled 55 miles per hour × 3 hours = 165 total miles. The train headed for Des Moines traveled 70 miles per hour × 3 hours = 210 total miles. Adding the distances together gives you the number of miles apart the two trains were after three hours: 210 + 165 = 375. Another option: You can add the two rates of speed (55 + 70) and multiply the sum by 3 hours (125 × 3 hours = 375).
