Question

A team recently launched a model rocket and tracked its elevation over a one-minute flight. The data they collected includes the rocket's actual flight path as well as the recommended minimum and maximum altitudes for optimal performance. This data is summarized in the graph below:

Based on the information above, answer the following questions:

The moment the rocket first exceeded the recommended maximum altitude was at seconds.

The time interval with the largest altitude gain during the flight was between seconds.

kingbucky · Answer

The graph shows the rocket’s flight path, recommended minimum, and maximum altitudes.

First exceeds maximum altitude: The flight path crosses the recommended maximum between 40 and 50 seconds.   
  Largest altitude gain: The steepest slope (highest rate of change) occurs between 40 and 45 seconds.

Solution:

1. The moment the rocket first exceeded the recommended maximum altitude was at  47  seconds.

2. The time interval with the largest altitude gain during the flight was between  40 and 45  seconds.

It's a pattern and trend graph where, if we closely look at the region, we can easily locate where the recommended maximum altitude is 47 secs or the largest altitude gain falls in the 40-45 secs region. We need a simple observation.

Hi  poojaarora1818 
Could you please explain how did you decide 47sec and 53sec? I am still unclear with this.

poojaarora1818 · Answer

Please check the recommended maximum altitude curve(Dark Blue), falling from 40 seconds to 60 seconds. The question here asks us to locate the first exceeded the recommended maximum altitude, which should be the maximum at 47. Could you see that?

Thanks  poojaarora1818 
If I am not mistaken, it is the intersection of light blue and dark blue coloured lines right?

Could you see a dot before the intersection of the light and dark blue curves?

Q1. Ans: 47 sec

Bismuth83 · Answer

1. We are asked to  analyze the graph and answer the following questions on the flight's path .

2. Note that initially the graph of the actual flight starts out under the recommended maximum. So, the first time it exceeds the maximum altitude is when the two graphs, light-blue and dark-blue, intersect. This happens in the interval from 45 to 50 seconds and is reasonable to say at around 47 seconds.

3. Looking at the answer choices, we can understand that the time interval being considered is 5 seconds in length. The largest altitude gain, in other words, is the largest upward spike in the light-blue graph. This can clearly be seen in the interval from 40 to 45 seconds.

4. Our answer will be:   D1 - 47 and D2 - 40 and 45 seconds  .

Need explanation for second, I thought it was highest b/w 50-60sec

BongBideshini · Answer

The time interval with the  largest altitude gain  during the flight = the interval gives you the sharpest positive slope. From the graph we can easily observe that the slope is sharpest between 40-45 seconds. 
 So, answer 40-45 seconds
