Question 1020780: Sophie travels to work by diesel train
The diesel train takes 81 minutes to do the journey.
Sophie sees an advert for a new high speed train
The advert says it will reduce her journey time by at least 32 minutes
The speed of the high speed train is 225kph
The speed of the diesel train is 125kph
Sophie uses this rule to check the advert
HT=dt
H= speed of the high speed train in Kph
D= speed of the diesel train in kph
T=time the journey takes in minutes using the High speed train
T=time the journey takes in minutes using the diesel train
You can put this solution on YOUR website! 81/60=1.35 hours by diesel
1.35 x 125=168.75 kilometers traveled.
168.75/225=.75 hours=45 minutes by high speed
81-32=49 minutes most time allowed according to advertisement.
You can also use the ratio of the trains speeds to measure the time saved:
125/225 x 81 minutes=45 minutes traveling time
81-45=36 minutes saved!!!!!!!
