Question and options
Two missiles speed directly towards each other, one at 12000 miles per hour and the other at 18000 miles per hour. Initially they are at a distance of 1115 miles from each other. How far apart they would be exactly 30 seconds before they collide?
- 50 Miles
- 100 Miles
- 250 Miles
- 11.15 Miles
Answer and explanation
Correct answer: C - 250 Miles
Closing speed = 12000 + 18000 = 30000 mph = 500 miles per minute. In the last 30 seconds they cover 250 miles, so they are 250 miles apart. The initial distance is irrelevant.
