First number = X
Second number = 8X
Third number = X - 3  

The equation would be
X + (8X) + (X - 3) = 207 

X + (8X) + (X - 3) = 207

X + 8X + X - 3 = 207

10X - 3 = 207

10X = 207 + 3

10X = 210

X = 21

First number = 21
Second number = 8 * 21 = 168
Third number = 21 - 3 = 18

During a Team scavenger hunt event, the average number of steps taken was 1800. Calculate the distance traveled using 10,000 ste
astra-53 [7]

Answer:

The average speed was of 2 miles per hour.

Step-by-step explanation:

Average speed:

Average speed is distance divided by time.

Distance:

Solved by proportions, using rule of three.

1800 steps - x miles

10,000 steps - 5 miles

10000x = 5(1800)

x = \frac{9000}{10000}

x = 0.9

Distance of 0.9 miles.

Using a time of 27 minutes to complete the event, calculate your average speed.

Distance of 0.9 miles in 27/60 of an hour. So

d = \frac{0.9}{\frac{27}{60}} = \frac{60(0.9)}{27} = 2

The average speed was of 2 miles per hour.
