The 25-mph zone is 150 yards long. How much time did the student save (in seconds) by speeding past the school

Time = 12.27seconds

Explanation:

Given

Speed = 25miles/hour

Distance = 150 yards = 150(0.000568182)miles

Distance (in miles) = 0.0852273miles

Get the time

Speed = Distance/Time

Time = Distance/Speed

Time = 0.0852273/25

Time = 0.0034hours

Time = 0.0034 * 3600secs

Time = 12.27seconds
