Allushta [10]

Answer:

Bess has been keeping track of the storm for 14 hours.

Step-by-step explanation:

The tropical storm has been moving at 15 miles per hour.

Bess recorded that the storm moved 135 miles yesterday and 75 miles today. Total distance covered by storm is

135+75=210

The relationship between distance speed and time is defined as

speed=\frac{distance}{time}

15=\frac{210}{time}

time=\frac{210}{15}

time=14

Therefore, Bess has been keeping track of the storm for 14 hours.
