A train moves 320 m320\,\text{m} due east in 16 s16\,\text{s}. Which statement about its average speed vavgv_{\text{avg}} and the magnitude of its average velocity ∣vˉ∣|\bar v| is correct? a) vavg>∣vˉ∣v_{\text{avg}} > |\bar v| b) vavgv_{\text{avg}} and ∣vˉ∣|\bar v| cannot be compared without specifying direction c) vavg=∣vˉ∣v_{\text{avg}} = |\bar v| d) vavg<∣vˉ∣v_{\text{avg}} < |\bar v|
