HOW TO PASS THE ARMY OFFICER
SELECTION BOARD (AOSB)
In order to help you prepare for the AOSB main board we will provide you with a brief tutorial on how to answer speed, distance and time tests. An ability to answer these questions is crucial to your success during the Army Officer selection process.
Accuracy and agility in speed, distance, and time calculations will help you perform well, both in the aptitude and planning exercises. This chapter provides a tutorial on the best way to approach these questions and has a number of different examples at varying difficulties for you to work through.
SPEED, DISTANCE, TIME TUTORIAL
When trying to solve these problems it is important to consider four variables: speed, distance, time and wind. Try not to get too worried as three of these variables will always be known. The easiest way to solve these equations is to use the following formulas:
The triangular diagram above helps you to remember the formula. If you place your thumb over the variable you are trying to discover, you will then see the equation required. For example if we wanted to obtain the time, placing your thumb on time would show that you would need to divide distance by speed.
SAMPLE ARMY OFFICER AOSB QUESTION 1
A plane travels 600 miles in 3 hours. What is the plane's speed?
Formula: Speed = distance ÷ time
Speed = 600 ÷ 3 = 200 mph
SAMPLE ARMY OFFICER AOSB QUESTION 2
A plane is flying at 300 knots for 70 minutes. What is the distance?
With this problem it is important to remember to work in minutes. So, 300 knots = 5 miles per minute (300 ÷ 60).
70 (minutes) × 5 = 350 miles
You can use the formulae but you need to convert the minutes into hours and remember that 0.1 = 1/10 of 60 minutes:
Formula: Distance = speed × time
Distance = 300 × 1.1666r= 350
