B) 2.5 hours , because 8 mph is 1 hour and the another 8mph is 1 hour 8+8mph =16mph 1+1hr=2hr half of 8 is 4mph is .5hr so therefore 8+8+4=20mph 1+1+ 30mins= 2.5hr

Answer:

2.5 hours

Step-by-step explanation:

20 ÷ 8 = 2.5

we have to divide the 20 by the 8 to figure out the amount of time and because Joey rode at 8 mph and traveled 20 miles than if you divide the miles traveled (y) by the rate (m), then you would get the amount of time it took (x); keep the slope intercept formula, y = mx + b, in mind

since there wasnt a y-intercept then you can ignore the b, but if you plug in the numbers for the variables then it would be right

20 = 8(2.5)

20 = 20
