The length of a bridge is 140 m. The length of each of Robert's paces is 55 cm.
Sindrei [870]

Answer:

255 steps

Step-by-step explanation:

They give us the length of the bridge and the length of each step of Robert, therefore we must divide these values to find the number of steps necessary, but first we must pass the distance of the bridge to centimeters:

140m * 100cm / 1m = 14000

Therefore the bridge would have a length of 14000 centimeters, we divide:

14000/55 = 254.54

Which means that Robert take at least 255 steps to fully walk the bridge.

Brandy set her watch 4 seconds behind and it falls behind another 1 second every day. How many days had it been since brandy las
kari74 [83]

Answer:

18 days

Step-by-step explanation:

Let x represent number of days.

We have been given that Brandy's watch falls 1 second every day. So Brandy's watch will fall 1x seconds behind in x days.

We are also told that Brandy set her watch 4 seconds behind, so Brady's watch will be behind by total x+4 seconds in x days.

Since Brady's watch is 22 seconds behind, so we will equate x+4 by 22 to solve for x as:

x+4=22

x+4-4=22-4

x=18

Therefore, Brandy set her watch 18 days ago.
