During the 1840's many came to California in search of gold. They began to come by wagon, horses, and foot. They came in large families and sometimes only friends.
Since with have both the distance and the velocity of both cars, we can calculate their velocities, which is distance/time.
Roger:
2 miles in 7.5 minutes -> 
2 miles in 0,125h -> 
Natalie
2 miles in 6.5 minutes -> 
2 miles in 0,1083h -> 
With their velocities in hand you can draw your own conclusions ;)
