There isn't enough information to give you a definitive answer. We also need to know in which direction they are riding.
If they are both riding in a straight line in the same direction, they will be 3 miles apart at the end of the first hour, 6 miles apart at the end of the second our, and 23 miles apart at the end of 7 hours and 40 minutes.
If they are both riding in a straight line in opposite directions, they will be 17 miles apart after the first hour, and 23 miles apart after 1 hour, 21 minutes, and 10.6 seconds.

Two people leave simultaneously from the same starting point biking in opposite directions Linda bikes at 7 mph and Dave bikes at 9 mph how long will it be until they are 24 miles apart?
After 1 hour, Linda will be 7 miles from the starting point, and Dave will be 9 miles away from that point but in the opposite direction. So they will be exactly (9+7=) 16 miles apart after 1 hour. They are moving apart at a rate of 16 mph. After 1.5 hours they will be exactly 24 miles apart.
Victoria and Margaret are 625 miles apart and traveling straight towards each other If Victoria's speed is 55mph and Margaret's speed is 70mph how many hours will it be until the two meet?
So this took me a while but the answer is five hours because you divide 625 by 55+70 and get five
2 trains 50 miles toward each other bird?
This is a classic math problemThe question goes something like this:Two trains are travelling toward each other, one at 10 miles an hour travelling east, the other at 15 miles an hour travelling west, and they are 50 miles apart. A bird is flying at 45 miles an hour, that starts with the eastward train and also heads east, when it reaches the westward headed train it heads back to the other train until it reaches it, then turns around again until it reaches the first train and so on, until the point in time the trains meet. The question then asks, how far does the bird travel before the trains meet?The Answer:This is ultimately a trick question. All the different speeds and distances are there to confuse you, it is actually a question about time. You simply first find how long it takes the trains to meet. In this case, where they are 50 miles apart and moving together, their total speed to cover the 50 miles is 25 miles/hour. Thus it takes 50/25=2 hours for the trains to meet. We know the bird is travelling at 45 m/hr this entire time so we calculate 45x2=90 miles travelled during this time period. This is all the question is asking, we do not have to find out how many times the bird goes back and forth or anything else of that nature.
How many miles is 255 miles at 35 mph?
255 miles is 255 miles - whatever the speed. At least until you get to Lorentz contraction which kicks in due to relativity when you are travelling close to the speed of light. At 35 mph the Lorentz contraction is less than a quadrillionth so probably less than the measurement error.
