Question

The equation for the speed/distance
of a tornado is s = 93 log(d) + 65.
If the speed is 190 mph, what is the distance?

Answer 1

Step-by-step explanation:

S = 93 log (d) + 65; S = wind speed; d = distance traveled by tornado

A) tornado travels 130 miles = d; find S

S = 93 log10(130) + 65

S = 261.6 mph rounds up to 262 mph

Answer 2

Answer:

• 22 miles

Step-by-step explanation:

• s = 93 log(d) + 65  and  s = 190

• 93 log(d) + 65 = 190
• 93 log(d) = 125
• log (d) = 125/93
• log (d) = 1.344 (rounded)
• d = 10^1.344
• d = 22 miles (rounded)
