Her total distance travelled is
Her average speed is mph
The total time is 4 2/3 hours or 4.67 hours
Therefore using the general formula distance=velocity x time,
x
x
miles

Hello, Afterme!
Mary drove from Amity to Belleville at a speed of 50mph.
On the way back she drove 60mph.
The total trip took 4 2/3 hours of driving time.
What is the distance between the 2 cities?
Going from A to B, Mary drove miles at 50 mph.
.Her time was: . hours.
Going from B to A, Mary drove miles at 60 mph.
. . Her time was: . hours.
Here total time was: hours.
There is our equation! . . .
Got it?
For some reason, you get a slightly different answer between my way and Soroban's way. I think Soroban's way is correct - does that mean there is a flaw in my logic?
Just re-did this problem using different numbers with a known distance, and I can confirm that my logic is incorrect. Use Soroban's solution technique.
