Answer:
300 meters per minute
Step-by-step explanation:
Step 1
Determine the fraction of the total distance for each part of the race.
Given:
1st part of race = 4/9 of total distance
2nd part of race = 2/5 of remaining distance
Step 2
Determine the distance of the third part of the race.
Given:
time = 15 minutes
speed = 300 meters per minute
Step 3
If the third part of the race (which is 1/3 of the total distance) is 4500m, then the distance of the whole race is:
Step 4
Determine the distance of the 1st part of the race:
Step 5
Determine the speed of the 1st part of the race:
Given:
time = 20 minutes
distance = 6000 m
389,422 rounded is 400,000.
Answer:
The first image.
x | y
-4 | 0
0 | 20 <--- When x = 0, the y value is the y-intercept.
4 | 40
8 | 60
Step-by-step explanation:
To check the slope, we can use the equation (y₂ - y₁) ÷ (x₂ - x₁) using any two pairs given. For this example, I'll use (-4, 0) and (4, 40).
x₂ y₂ x₁ y₁
(0 - 40) ÷ (-4 - 4)
(-40) ÷ (-8)
<u>Slope = 5</u>
<u></u>

It will take Ahmad 12 hours to drive 864 miles
Step-by-step explanation:
- Step 1: Find the speed of Ahmad.
Distance = 360 miles
Time = 5 hours
⇒ Speed = Distance/Time = 360/5 = 72 miles/hour
- Step 2: Find the time required to drive 864 miles
⇒ Time = Distance/Speed = 864/72 = 12 hours
