Question 709242
The constant climbing rate is the cahnge in distance divide by the cahnge in time.
The change in time from 1:00pm to 2:30pm is 1.5 hours.
Let climbing rate = R
{{{R = (6040 - 5620)/(1.5)}}}
{{{R = 420/1.5}}}
R = 280ft per hour
You can also divide that number by 60 to convert it to feet per minute.
