Answer:

always try to draw a diagram first

Step-by-step explanation:

Jana ran The first 3.5 miles in 1/3 of an hour. remember the problem tells us that we want our answer in miles per hour or mph. so we have to set up our problem so that our units match in the end. The diagram above shows 3.5 mi over 1/3 hour. so we must divide 3.5 miles by 1/3 hour

note:

[tex]3 \frac{1}{2} mi = \frac{7mi}{2} [/tex]

therefore

[tex] \frac{7mi}{2} \: \div \: \frac{1hr}{3} = [/tex]

[tex] \frac{7mi}{2} \times \frac{3}{1hr} = \frac{21mi}{2hr} = 10 \frac{1}{2} \frac{mi}{hr} [/tex]
