The altitude and time of both Malik and Mila are provided in function form. The rate of climb can be gotten by evaluating the slope of the functions/graphs.
To calculate the slope, we use the formula:
Mila's Ascension:
We have the following parameters from the table:
Hence, we can calculate the rate of climb to be:
Therefore, Mila ascends at 721 ft/h.
Malik's Ascension:
We have the following parameters from the graph:
Hence, we can calculate the rate of climb to be:
Therefore, Malik ascends at 693 ft/h.
The difference between both ascension rates is how much faster one is going than the other. This is given to be:
ANSWERS:
1) Mila is climbing at a faster rate.
2) Mila is climbing faster than Malik at a rate of 28 ft/h.
