t is 170 miles from Bruce’s house to the city where his brother lives. On his last trip to visit his brother, he drove for 2 hours at 55 miles per hour. Then he came to some very bad road construction. The rest of the trip took 2 hours. How many miles per hour did Bruce drive for the rest of the trip?

Respuesta :

He Drove 30Mph For The Rest Of The Ride
170-(55*2)=60
60/2=30Mph
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
