Anthony plans to ride 175 km on his bike and Samanta plans to ride 250km. They both plan to complete their journeys in a whole number of days.
How many kilometres could each person travel if they both ride the same number of kilometres each day.
How many days will each person have to ride for each common factor you found in part (a). Explain

175 = 5*5*7
250 = 2 * 5 * 5 * 5
I assume they both plan to complete their journey in the same whole number of days...
The only factors in common are 5 or 25.
Using 5 days, then Anthony needs to ride 35km/day, and Sam needs to ride 50km/day
If 25 days, then A=7km/day and S=10km/day.
I'd say they take 5 days.
