1.The table shows the number of miles driven over time. Time(hours):4 , 6 , 8 , 10 Distance(miles):204 , 306 , 408 , 510 Express the relationship between distance and time in simplified form as a unit rate. Determine which statement correctly interprets this relationship. A.51/1; your car travels 51 miles every 1 hour. B.204; your car travels 204 miles. C.1/51; your car travels 51 miles every 1 hour. D.10; your car travels for 10 hours .

Mercury:

unit rates ---> the rate at which unit y changes, per 1 unit x in this case, the unit rate for miles/time would be miles/1 hour, which narrows us down to choices A+C now, to find the speed in miles/hr, simply take any set of corresponding time and speed values (ex: 204 miles and 4 hours) and divide miles/hours to get the unit rate
