Answer:
The change in height is 6/10 miles per hour and the entire descent will last 150 minutes (2 hours and 30 minutes)
Step-by-step explanation:
The gilder started 1 1/2 miles above the ground, in other words, it started miles above the ground. After 60 minutes it is now
miles above the ground.
Therefore, the change in height in one hour is: miles.
Now, we know that the glide descends at a rate of 6/10 miles per hour, we can solve the second part of the problem using the rule of three (or proportions)
<em>If it takes it 60 minutes to descend 6/10 miles, how long it will take it to descend 15/10 miles?</em>
60 minutes --- 6/10= .6
x minutes ---- 15/10= 1.5
Therefore minutes
Thus, the entire descent will last 150 minutes.
