zepelin [54]
<h3>- - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - </h3>

➷ Use the formula: distance = speed x time

Jordan's distance = 55 x 6

Jordan's distance = 330 miles

Matt's distance = 60 x 3

Matt's distance = 180 miles

330 + 180 + 82 = 592

In short, the answer is 592 miles
