A road lies between two parallel buildings. A motorist travels with speed 36 km/h on the road and hits the horn. He heard the echo 1 second later. The speed of sound is 330 m/s
a. Find the distance of the building
b. When will he hear the second echo?
2d = v.t
The Attempt at a Solution
The first echo will come from the nearest building and the second echo will come from the further building.
a. the distance of nearest building to motorist = d1
2 d1 = v.t
d1 = 115 m
I don't know how to find the distance of further building to the motorist and is the speed of motorist being used in the calculation?
