Problem 2-62 - Distance and speed - Part 4 (a)

A truck travels at \(80\; km/h\) for \(30\; min\), then at \(60\; km/h\) for \(1.5 \;hr.\) Assuming 2 significant digits in the given numbers, calculate the truck's
(a) total distance traveled, and
(b) average speed.

Accumulated Solution

\(\mathrm{speed = \frac{d}{\Delta t }\\ d = (speed) \Delta t}\)

No. The time unit in the speed is \(h\) not \(min\).
