A reconnaissance drone is flying at an altitude of 500 feet. If it ascends at a rate of 75 feet per minute for 8 minutes, what is its new altitude?
- A575 feet
- B1100 feet
- C650 feet
- D1200 feet
Show answer & explanationAnswer & explanation
Correct answer: B. 1100 feet
First, calculate the total ascent: 75 feet/minute * 8 minutes = 600 feet. Then, add this to the initial altitude: 500 feet + 600 feet = 1100 feet.
Why the other options are wrong
- A. This is the altitude after 1 minute of ascent.
- C. This is an incorrect calculation, possibly 500 + 75 + 75.
- D. This is an incorrect calculation, possibly 500 + (75 * 9).
Multi-step Arithmetic (Rate & Initial Value)
Solving a problem that combines multiplication (for a rate) and addition (to an initial value).
- Calculate the change based on rate and time first.
- Add or subtract the change from the initial value.
- Follow order of operations.
Memory trick: Rates Add Up to Reality.
