than Graham and travels at a speed of 8 mph while Graham travels at 2 mph. How long will take until they
meet?

2 and 1/2 hours

you want to add the total distance they taveled together, which would equal 25. So, 8 times 2.5 hours = 20 and 2 times 2.5 hours = 5. 20+5=25

Answer:

To determine how long it will take until Mrs. Jones and Graham meet, we can use the concept of relative speed, which is the speed at which the two objects are moving relative to each other. In this case, Mrs. Jones is moving at a speed of 8 mph, and Graham is moving at a speed of 2 mph.

We can use the formula:

Time = Distance / Relative Speed

where Distance is the distance between Mrs. Jones and Graham, and Relative Speed is the speed at which they are moving relative to each other.

Since we know that Mrs. Jones and Graham are 25 miles apart, and we know their speeds, we can plug those values into the formula to solve for Time:

Time = 25 miles / (8 mph - 2 mph)

Time = 25 miles / 6 mph

Time = 4.17 hours

Therefore, it will take approximately 4 hours and 17 minutes for Mrs. Jones and Graham to meet, assuming they are moving at the speeds you provided.
