Jordan starts at his home and bikes along a country road. He bikes at a constant speed. Twenty minutes later he passes Stephanie's house; he knows he is 2 kilometers away from his home. Another one of his friends, Jacob lives 4 kilometers further down the same road.
A) How much longer would Jordan have to ride his bike to reach Jacob's house? (He would have to ride another 20 minutes(?) <--That was my answer but I am unsure of it because I don't know the total distance travelled in the beginning hence my confusion of whether I am correct or not)
B) How long will Jordan take to ride his bike 10km?
