PLS HELP ILL GIVE BRAILIEST + 20 PTS

What is the displacement of a car which travels at a steady velocity of
60 km/h
(a) for 3 h
(b) for 1/2 h?

Answer 1

(a) 180 km

(b) 30km

Step-by-step explanation:

To find displacement (in this case, kilometers) you need to convert km/h to km, this can be done by multiplying by the amount of hours:

`(60km)/(h)*3h=60km*3=180km \\(60km)/(h) *h/2 = 60km/2=30km`

(The h/2 term came from 1/2*h, since half an hour is h*1/2)
