a car travel for 1 hour that means 90.km per hour and 20 minutes that should be divided as 90 divide by 3 as 60 divided by 3 is 20 so 90 by 3 is 30 so 90km + 30km is equal to 120 km

Answer 2

      120km

Explanation:

Time of travel =  1 hour and 20 minutes = 1 + 20/60hrs = 1 + 1/3 hrs = 3+1 /3hrs Time of travel = 4 / 3 hrs

Speed of car = 90km/hr

Speed = distance / time

distance = speed × time

distance =90km/hr × 4/3 hrs

distance =30km/hr × 4 hrs

distance =30km × 4

distance = 120km
