10 point question......

Answer:
He traveled for 12 hours
Step-by-step explanation:
583.2 miles divided by 48.6 miles = 12 hours
Answer:
They have traveled 12 hours
Step-by-step explanation:
We know that distance equals rate multiplied by time.
D = rt
The distance equals 583.2 and the rate is 48.6
Substituting these into the equation
583.2 = 48.6 *t
Divide each side by 48.6
583.2/48.6 = 48.6/48.6 *t
12 = t
They have traveled 12 hours
