Problem with proximity sensor times

It was discussed how to deal with the measurement times of the proximity sensors.
The sensors send an ultrasonic pulse when triggered and write a digital 1 to the echo pin until the pulse has come back.
Assuming an obstacle is in 3.4m distance, the sonic has to travel 6.8m before it comes back to the sensor. Sonic speed is about 340m/s which equals a time of 20ms. With 10 sensors the maximum
