Lag Distance or Reaction Distance given Stopping Sight Distance Solution

STEP 0: Pre-Calculation Summary
Formula Used
Lag Distance = Stopping Sight Distance-Breaking Distance
LD = SSD-BD
This formula uses 3 Variables
Variables Used
Lag Distance - (Measured in Meter) - Lag distance is defined as the distance travelled by the vehicle before applying the break and after seeing the object.
Stopping Sight Distance - (Measured in Meter) - Stopping Sight Distance is defined as distance provided on the road before a sharp turn.
Breaking Distance - (Measured in Meter) - Breaking distance is defined as the distance traveled after applying brake till the vehicle stops.
STEP 1: Convert Input(s) to Base Unit
Stopping Sight Distance: 160 Meter --> 160 Meter No Conversion Required
Breaking Distance: 40 Meter --> 40 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
LD = SSD-BD --> 160-40
Evaluating ... ...
LD = 120
STEP 3: Convert Result to Output's Unit
120 Meter --> No Conversion Required
FINAL ANSWER
120 Meter <-- Lag Distance
(Calculation completed in 00.004 seconds)
