You can put this solution on YOUR website!
You use v=d%2Ft relation twice.
At 45 mph:
45=2%2Ft
t+=+2%2F45 hours
At 65 mph:
65+=+2%2Ft
t+=+2%2F65 hours
The difference is:
2%2F45+-+2%2F65 hours
hours or approx. 0.82 minutes or approx. 49.23 seconds. VERY SMALL DIFFERENCE. NOT WORTH SPEEDING THROUGH A WORK ZONE.
