The stoplights on a street are designed to keep traffic moving at 25 mi/h. The average length of a street bloc?

The average length of a street block between traffic lights is about 80 m. What must be the time delay between green lights on successive blocks to keep the traffic moving continuously? There are 1.609 × 10^3 m in a mile. Answer in units of s

1. Time to do 80 m = d / v = 80 / 11.17 = 7.16 s That would be the delay from one light to the next. Then they should stay gren for that long to let the slug of traffic clear.
