# The car moves along the road to the bridge at a speed u = 72 km / h. At the initial moment

The car moves along the road to the bridge at a speed u = 72 km / h. At the initial moment, the distance from the car to the beginning of the bridge is L = 200m. At what distance s from the middle of the bridge will the car be located in t = 1 min. If the length of the bridge is L = 400m?

Given:
v = 72km / h = 20m / s,
L1 = 200m,
L2 = 400m,
t = 1min = 60s;
Find: d -?
With uniform movement in time t, the car will cover the distance:
s = v * t = 20m / s * 60s = 1200m;
The car will pass the center of the bridge and will be at a distance from it:
d = s – L1 – L2 = 1200m – 200m – 400m = 600m.
