A yacht sailed at a steady speed for 0.5 hours, passing a cruise ship that was traveling at 25
kilometers per hour. During that time, the yacht traveled 50 kilometers. What was the yacht's
speed?

Respuesta :

The speed of the yacht : 100 km/h

Further explanation  

Linear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration  

  • At constant velocity motion:  

the speed of vo = v = constant

acceleration = a = 0  

Δx = vt or x = xo + vt  

An equation of constant velocity motion  

[tex]\large {\boxed {\bold {x = v \times \: t}}}[/tex]

x = distance = m  

v = speed = m / s  

t = time = seconds  

A yacht sailed at a steady speed for 0.5 hours, and traveled 50 kilometers

so the velocity/speed:

[tex]\tt v=\dfrac{x}{t}\\\\v=\dfrac{50~km}{0.5~h}=\boxed{\bold{100~km/h}}[/tex]
