Answer:
F is reduced by 31%
Step-by-step explanation:
F = 1/(d²)
now, we increase the distance by 20% (multiply by 1.2).
F new = 1/(1.2×d)² = 1/(1.44×d²) = (1/1.44) × (1/(d²)) =
= 1/1.44 × old F = 0.69 × old F
100 - 69 = 31%
Answer:
12 times (double the times since we are doubling the minutes)
Step-by-step explanation:
2/6 = 4/x
Use cross multiplication
2x = 6*4
2x = 24
x = 12
