Question 225824
If I were traveling at 253 mph, how many feet will I travel in 1 second?


Step 1.  Convert 253 mph to feet/sec.


Step 2.  5280 feet = 1 mile 


Step 3.  1 hour = 60 minutes = 60 minutes*60 seconds/minute = 3600 seconds


Step 4.  {{{253*miles/hour=(253*miles/hour)*(5280*feet/mile)*(1*hour/3600 seconds)=253*5280/3600*feet/sec=371.1*(feet/sec)}}}


Note the units of miles and hours cancel they these units appear both in the numerator and denominator.


Step 5.  ANSWER:  Since {{{353*(miles/hour)=371.1*(feet/sec)}}}, then in 1 second you travel 371.1 feet.



I hope the above steps were helpful.
