Velocity of Vehicle given Lag Distance or Reaction Distance Solution

Follow our step by step solution on how to calculate Velocity of Vehicle given Lag Distance or Reaction Distance?

FIRST Step Consider the formula

V b = \frac{LD}{t}

Next Step Substitute values of Variables

∴

V b = \frac{27.7m}{2.5s}

Next Step Prepare to Evaluate

∴

V b = \frac{27.7}{2.5}

LAST Step Evaluate

∴

V b = 11.08m/s
