Answer:
Marc: 8 meters & 4 seconds
Prisha: 6 meters & 3 seconds
Explanation:
Marc: If Marc travels 8 meters in 4 seconds it means that he has a speed of 2m/s
Prisha: If Prisha travels 6 meters in 3 seconds it means that she has a speed of 2m/s
To find speed we simply have to divide distance by time
The way that I figure out the answer was by trial and error. This is when we have to get random numbers and try them.
2 seemed a reasonable answer as it couldn't a number such as 5 as there is only 1 factor of 5 between 0 and 9. There are 4 factors of 2 between 0 and 9
Hope this helps, have a great day!!
