(80 km/hr)(2.75 hr) (5 mi/8 km)
Can a mod please move this to the appropriate subforum?
Jodie travels at a speed of 80 km per hour for 2 hours 45 minutes. Work out how many miles she drives.
I understand 5 miles = 8 km but I don't know how to solve the question.
Sorry for my noobishness, thanks for the help!
So skeeter's line would read:
The units cancel out in the same way as numbers do. So in the ( ) is the distance the car travels in km. (The units hr cancel out by division.) This comes from the equation d = vt. Then the last factor converts km into miles. In this case the km cancels out.
