B. 340 metres
C. 350 metres
D. 360 metres

Answer :

Answer: 340m

Explanation:

Given that:

Streets are constructed from 10 m pieces;

A lamppost is placed at both ends and at every 10 m along its length ;

A lamppost is also placed at every notice board along its length :

Given that:

Einstein Street has 42 lamppost and 7 notice boards :

So,

7 lamppost for 7 notice boards :

Lamppost left = 42 - 7 = 35 lamppost

2 lamppost placed at both ends :

Lamppost left = 35 - 2 = 33 lamppost

Hence, the remaining is placed at 10 m along its length:

Hence, length of Einstein street :

33 lamppost each placed 10m from the starting lamppost = (33 * 10) = 330m

Distance between 33rd lamppost and the ending lamppost = 10m

Hence, total length = (330 + 10) = 340 m
