hi can you help me with this problem please, thank you.----------------- If the speed of an experimental car is decreased by 8km/h it completes a 140 km trip in 2 hours more than had it been traveling at its usual speed. Determine its usual speed.

how do you get negative 50? how do you know to subtract instead of add?

[superkrazysoccergal]

@thmking because you have to cancle out 50. -50+50=0

Pulling an all nighter once again, and you are just in time for a great technique I was strugling in right before my Final Exam. Wow! For this to be such a difficult semester due to uncontrolled circumstances, I believe everything will turn out just fine. Thank you Jesus!

[ldn37]

but overall it is still quite helpful in some questions so thanks

[ldn37]

there is a easier method

3h --> 50x3=150

65-50=15(every hour difference)

150/15=10

10h

Super way to teach math. Use of video is an excellent idea.
