We can start by calculating Apollo's original speed. If he traveled 48 leagues in 3 days, then his speed was:
48 leagues / 3 days = 16 leagues per day
Next, we know that Apollo tripled his rate, which means his new speed is:
16 leagues per day x 3 = 48 leagues per day
To find out how long it will take him to travel 336 leagues at this new speed, we can use the formula:
time = distance / speed
In this case, the distance is 336 leagues, and the speed is 48 leagues per day. So we have:
time = 336 leagues / 48 leagues per day = 7 days
Therefore, it would take Apollo 7 days to travel 336 leagues at his new speed.
