Carly Long · Answer 1

He Drove 30Mph For The Rest Of The Ride

170 - (55*2) = 60

60/2=30Mph

Giuliana Peters · Answer 2

Whole distance = 170 miles

distance before the bad road construction

time = 2hrs speed = 55 mile per hour distance = speed * time = 55 * 2 = 110 miles

Remaining distance = 170 - 110 = 60 miles

Time = 2 hours

Speed = distance / time = 60 / 2 = 30

Therefore his distance is 30 miles per hour
