Answer:
46.67m/h
Step-by-step explanation:
I have only 2 hours so my maximum hours are 3. I have to be in there between 0 and 3 hours so if I reach before 3hours I'm very fast but if I reach at the 3rd hours my hours were ending so the smallest speed that I need to run is
140 miles in 3 hours
v =d/t
v =140miles/3hours
v = 46.67miles/hour
