The first thing you do is calculate how many miles the person run per minute then you multiply by the time in this case 10. Let me show you:
6mi/1h*10 We know that an hour is the same that 60 minutes, so we simplify:
6mi/60min*10 Then we found how many miles the person runs per minute, you divided and we found that the person runs 0.1 miles per minute, we simplify:
0.1mi/min*10 Now you calculate 10 times 0.1 and that's 1 mile in 10 minutes.
Now for the cyclist is the same :
12mi/60min*10= 0.2mi/min*10= 2 miles in 10 minutes.
Finally you find the amount of miles and write your answer : If they maintain their speeds, they will be 3 miles far from each other 10 minutes after passing.
