Answer:
b. (1, 13).
Step-by-step explanation:
Here's a pic of my work. You can put either equation on the other side of the equal sign, because they both equal Y. therefore, they equal each other.
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 :)
