# 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 $min$.

Try again.
