the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality
however, is the same cat wearing different costumes.
to get the slope of any straight line, we simply need two points off of it, so let's use the ones provided in that
let's notice, is negative since the population decreased.
Alright, lets get started.
Ben left at 8:00 AM and Al left at 11:00 AM.
Suppose dispatcher retrieves data after t hrs when Al left SD.
We know the average speed of Al = 40 miles per hr
So, distance covered by Al = Time * speed
Distance covered by Al = 40 t
We know average speed of Ben = 20 miles per hr
As we know Ben left SD 3 hrs before, time taken by Ben will be 3 hrs higher than AL means (t+3)
So distance covered by Ben =
Total distance covered by both will be =
Total distance covered by both will be =
Total distance covered by both will be =
But as per given in question, total distance covered by both is 240 miles.
Hence making both equal,
Subtracting 60 from both sides
Dividing 60 in both sides
t = 3 hrs
It means it was 11:00 AM + 3 hrs means 2:00 PM when dispatcher retrieve data. : Answer
Hope it will help :)
