Answer: The answer is 0.25 miles.
Step-by-step explanation: Given that my friend started walking at a speed of 3 miles per hour and I started 5 minutes after him at a speed of 4 miles per hour. We need to find the number of miles my friend travelled when I started walking.
Since I started 5 minutes after than my friend, so we are to find the distance travelled by my friend in 5 minutes.
In 1 hour, i.e., 60 minutes, distance travelled by my friend = 3 miles.
In 1 minute, distance travelled by my friend is

Therefore, distance travelled by my friend in 5 minutes will be

Thus, the answer is 0.25 miles.
Answer:
Step-by-step explanation:
- 6(x - 7)= 2x + x + 9
- 6x - 42 = 3x + 9
- 6x - 3x = 9 + 42
- 3x = 51
- x = 51/3
- x = 17
w - width
2w + 5 - length
w + w + (2w + 5) + (2w + 5) = 6w + 10 - perimeter
34 cm - perimeter
The equation:
6w + 10 = 34 <em>subtract 10 from both sides</em>
6w = 24 <em>divide both sides by 6</em>
w = 4 cm
2w + 5 = 2(4) + 5 = 8 + 5 = 13 cm
<h3>Answer: Width = 4cm, Length = 13cm</h3>
