Answer:
43.6*10⁴
Step-by-step explanation:
4.9 * 10⁵ = 49*10⁴
then:
4.9*10⁵ - 5.9*10⁴ = 49*10⁴ - 5.9*10⁴ = (49-5.4)*10⁴ = 43.6*10⁴

Answer:
The rate of descent is 4 ft/min.
He will descent 24 ft in 6 min.
Step-by-step explanation:
Consider the provided information.
He starts at sea level and then descends 10 feet in 2 1/2 minutes.
First convert the mixed fraction as shown:

Therefore the rate of descent is:
The rate of descent = 
Hence, the rate of descent is 4 ft/min
Now find In 6 minutes, how much he will descent:

Hence, he will descent 24 ft in 6 min.
