A car travels in a straight line at 40 km/hr for 1 h and 60 km/hr for 2 h. A) How far does it travel? B) Find the average velocity.
Average velocity = Δx/Δt (change in distance/change in time)
The Attempt at a Solution
In solving for A, I got (1 h x 40 m/hr + 2 h x 60 km/hr) = 160 km/hr
For B, this is where I'm confused. I know that if I try to arrange it as suggested in the formula (160 km/hr/2-1 h), wouldn't this just leave me with the remaining distance and eliminating the unit for time? Or would that be correct? I feel like it would not be though as the formula suggests, average velocity is defined by change in distance per change in time. Any help is greatly appreciated!
