a car travels 1480 km in 13hr 24 min.
if car covers 3/5 of the journey at a speed of 148 km/hr,
find the speed of the car for the rest of the journey?
:
Change 13 hr 24 min to hrs: 13 + = 13.4 hrs
:
Find the distance traveled at 148 km/hr
* 1480 = 888 km
then
1480 - 888 = 592 km at an unknown speed (s)
:
Write a time equation; time = dist/speed
+ = 13.4
6 + = 13.4
= 13.4 - 6
= 7.4
s =
s = 80 km/hr on the rest of the journey
