spin [16.1K]

Answer:

$0\leq x\leq 6$

$0\leq y\leq 48$

Step-by-step explanation:

we are given

speed =8 mph

time = 6 hours

so, we have

$x=6$

now, we can find distance

distance = (speed)*(time)

$distance=8\times 6 miles$

$distance=48 miles$

so, we have

$y=48 miles$

so, our range for x and y can be

$0\leq x\leq 6$

$0\leq y\leq 48$
