Question

a car at point A travels at a constant velocity of 80km/h towards point B. the distance between the points is 160km. how long does it take to get from point A to point B

Answer 1

t = 7200.07seconds or 2 hours

Step-by-step explanation:

given:

velocity (v) : 80km/h = 80 × 1000 m/ 60 × 60 s

= 80,000m/3600s => 22.222m/s

distance(d) = 160km => 160 × 1000 = 160,000m

time(t) = ?

since v=d/t

therefore, t= d/v

t= 160,000/22.222

t= 7,200.07seconds

or t= 7,200/3600 = 2 hours.
