The points A, B, C and D all lie on the same line segment, in that order, such that the ratio of AB:BC:CDAB:BC:CD is equal to 1:4:1.1:4:1. If AD=18,AD=18, find CD. CD.

where is the figure

54 kilometers per hour

step-by-step explanation:

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
