nincompoop · Answer

determine the distance covered in 2.5 hours when the speed is at 60 miles an hour 
then try to figure out how many hours it will take for that distance to cover when the speed is at 70 miles an hour

nincompoop · Answer

or you can just do 60/2.5 = 70/x

anonymous · Answer

if we let time as t and speed as s, the equation will be
$$t=\frac{ k }{ s }$$ where k is the constant of proportionality...
