Question

1 Jack and Diane want to meet for breakfast. Jack walks 1.5 mph and Diane walks 1 mph. They started 5 miles apart from each other. How long does it take them to meet up?

anwers : jack take 3.33 hours and diane would take 5 hours

2 How far apart were they after 1 hour?

Answer 1

1.5mph (x) = 5m
x = 5:1.5 = 3.33 [hours]

1mph (x) = 5m
x = 5:1 = 5 [hours]

After one hour, with JACK’S Speed :
5m - 1.5m = 3.5m [far apart]

After one hour, with DIANE’S Speed :
5m - 1m = 4m [far apart]
