Answer:
1.Home:0 km to School:180 km
2.7:30 A.M
3. 3 Hours (From home to school) but if it's a round trip 6 hours,3 hours from Home to school
and 3 hours from School to Home = 6 Hours
3 hours + 3 hours =6 hours
4. 180 km ( Far from home to school) but if it's a round trip 380 km,180 km from Home to school and 180 km from school to home = 380 KM
180 km + 180 km = 380 km
