dumbcow · Answer

distance = rate * time
since Ted caught up they went the same distance just at different rates and times
Let r be trevons speed, then (r+10.4) is teds speed
Ted was driving for 3 hours
trevon was driving for 3+1.3 or 4.3 hours

set the distances equal
-> 4.3r = 3(r+10.4)
solve for r
