A car traveled at the rate of 70.km/hr for 2.5 hours in canada and then traveled at a rate of 65.MILES/hr for 3.2 hours in michigan. What was his total distance traveled in km? (1 miles=1.67km)

70*2.5 + 65*3.2*1.67= 522.36 kilometers

distance travelled in canada = 70 km/hr x 2.5 hrs = 175 km.
distance travelled in michigan = 108.55km/hr x 3.3 hrs = 347.36 km.
hence the total distance travelled = 522.36 km
