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.

Percent increase is 21%

Step-by-step explanation:

Initial cost of shoes = $72

New price of shoes = $87

Increase in price of shoes = New price of shoes - Initial cost of shoes

= 87-72

= $15

Percentage increase in price of shoes = ( Increase in price of shoes ÷ Initial cost of shoes) × 100

= \frac{15}{72}(100)=20.8\%

≈ 21%

So, percent increase is 21%
