Car travels 400 km in the first 3 hours of a trip. it stops for 2 hours and then travels final 250km in 1.5 hours. find the average speed of the car
-----
1st leg:
distance = 400 km ; time = 3 hrs
----
Stop time:
distance = 0 km ; time = 2 hrs
----
2nd leg:
distance = 250 km ; time = 1.5 hrs
-----
Average speed = (total distance)/(total time) = 650/6.5 = 10 km/hr
