Answer:

2 13/16

Step-by-step explanation:

given:

d = 150 miles

f = d = √8000a

a = ?

150 = √8000a

(150)² = (√8000a)²

22,500 ÷ 8000 = 8000a ÷ 8000

22,500/8000 = a

2

8000 ✓22,500

- 16,000

------------------------

6500

so

2 6500/8000 simplify by dividing the numerator and denominator by 500

a = 2 13/16
