Answer:

Step-by-step explanation:

The leftmost line segment has a slope of -2 and (-1,-1) is a point on the line.

Equation: y = -2x-3

middle line segment has a slope of 0 and y-intercept of -2.

Equation: y = -2

The rightmost line segment has a slope of 1.5. (5,0) is a point on the line.

y = 1.5(x-5) = 1.5x-7.5

The length of a bridge is 230 m. The length of each of Robert's paces is 75 cm.

wariber [46]

Answer:

307 paces

Step-by-step explanation:

First, lets convert Robert's pace to metres. (cm > m)

75cm = (75/100)m

= 0.75m

Number of Full Paces = Length of Bridge / 1 Full Pace

$\frac{230m}{0.75m} \\ = 306 \frac{2}{3} paces$

See , we must have full paces, and in this case we are finding the minimum number of paces, so we will be looking at the lowest possible whole number, which in this case, is 307 paces.
