Answer 1

Answer: 6m

Step-by-step explanation:

Given data:

Width of the strips on the cross walk = 0.4m

No of white strips on the cross walk = 8.

No of black strips = 7

Solution:

Since they are 8 whites, and the cross walks starts and ends with a white stripe.

This simply means they are 7 black stripes

Width of the cross walk

= 7 + 8 * 0.4m

= 15 + 0.4m

= 6m

Width of the cross walk is 6m.
