Question

If a car travels 216 kilometers in 4 hours, calculate its speed.

Answer 1

V=S/T

V=216km/4hr

V=54km/hr

Step-by-step explanation:

1km/hr = 5/18 m/s

54km/hr= X

X=5/18m/s * 54km/hr

1km/hr

X=15m/s(approximately)

Answer 2

15 m/s

Step-by-step explanation:

Speed(m/s) = distance(m)/time(s)

distance = 216 km = 216,000 m

time = 4 hours = 14,400 s

speed = 216000/14400 = 15 m/s
