Answer:
5 times
Step-by-step explanation:
Sam completes 3 rounds in 1 hour or 6 rounds in 2 hours.
Joe completes 5 rounds in 2 hours.
Now, both complete an integral number of rounds in 2 hours.
Thus, after starting, they meet each other for the first time after 2 hours.
Hence, they will meet every 2 hours.
Hence, in 10 hours they meet for 10/2 = 5 times
