1) in first place you need establish a relation of miles per hour , 15 miles / h
the total miles that Bess has been keeping track the storm is 75+135 =210
2) Now 15 miles ___ 1 h
210 miles ___x (h)
x(h) = 210 miles * 1 h / 15 miles = 14 hrs Bess has been keeping track of the storm
Answer: Bess had been keeping track of the storm for 14 hours.
Step-by-step explanation:
Since we have given that
Number of miles he recorded yesterday = 135 miles
Number of miles he recorded today = 75 miles
Total number of miles = 135+75=210 miles
Speed = 15 miles per hour
So, Time taken is given by
[tex]time=\dfrac{distance}{Speed}\\\\Time=\dfrac{210}{15}\\\\time=14\ hours[/tex]
Hence, Bess had been keeping track of the storm for 14 hours.
