Steve races to the nearest taco stand at lunchtime and sees that his pedometer recorded his peak speed at 75.175.1 cm/s. what was steve's peak speed in kilometers per hour?

Respuesta :

2.42 km was steve's peak speed in kilometers per hour.

Describe speed -

  • Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path.
  • In other words, velocity is a vector, whereas speed is a scalar value.

Given speed is 67.1 cm/s

we know that 1 cm = 10-² m

            and  1 m = 10-³ km

∴   1 cm = 10-5 ∴m

also          1 sec = 1/3600 hr

∴   67.1 cm/s  = [tex]\frac{67.1 * 10^{-5 km} }{\frac{1 hr}{3600 } }[/tex]

or  67.1 cm/s  =  2. 4156 km/hr  or 2.42 km
