Best ResponseYou've already chosen the best response.1the point (70,0)

Best ResponseYou've already chosen the best response.1what this means is that when x = 70, y = 0 x = time y = distance when the time is 70 minutes, the distance is 0 (ie you get to the destination)

Best ResponseYou've already chosen the best response.1notice in the table for car 1 how x = 70 and y = 0 pair up (first two rows, last column)

Best ResponseYou've already chosen the best response.1look at the graph of car 2. Where does the curve cross the y axis? you can also look at the table for car 2 and look for the y value when x = 0

Best ResponseYou've already chosen the best response.1yes so this is basically saying that at the beginning time (time t=0 minutes), the distance away from home is 70 km

Best ResponseYou've already chosen the best response.1the distance car 2 is away from the destination is 70 km

Best ResponseYou've already chosen the best response.1look at the car 2 curve do you see how it goes past x = 70 ?

Best ResponseYou've already chosen the best response.1x is greater than or equal to 0, but I don't see where the graph of car 2 stops. This is definitely one of those questions where not enough info is given
