@Hero please hurry and reply...
hero (hero):
\[\frac{30 \text{mi}}{\text{h}} = \frac{x\space\text{ft}}{\text{min}}\]
\[\frac{30 \text{(5280) ft}}{\text{60 min}} = \frac{x\space\text{ft}}{\text{min}}\]
\[\frac{30 \text{(5280) ft}}{\text{60 min}}\dot\ \frac{\text{min}}{\text{ft}} = x\]
\[\frac{30 \text{(5280)ft}}{\text{60 min}}\dot\ \frac{\text{min}}{\text{ft}} = x\]
hero (hero):
\[\frac{30(5280)}{60} = x\]

So the answer would be C? 880?

No one told you to pick c
hero (hero):
\[\frac{30(5280)}{60} = 2640\]
OpenStudy (anonymous):
Because 30 x 5280 divided by 60 would equal 2640.
Instead of multiplying I just divided 5280 into 60. Like a dummy. & Excuse me.. I made a mistake...

Okay thank you :) bye.
