La correcta respuesta es número D porque solo tienes que dividir los dos numeros
Subtract 120 every time but I don’t know the second one
Train A:
Distance (s) = 420 miles
Time (t) = 3 hours
Speed (v) = distance ÷ time = 420 ÷ 3 = 140 miles/hour
Train B:
Distance (s) = 420 miles
Time (t) = 2.25 hours
Speed (v) = distance ÷ time = 420 ÷ 2.25 = 186.7 miles/hour
A) m=-3
B) n=-17
hope this helps x
would love to have brainliest if it is right :)
