distance = rate x times; distance = 226 miles, time = 2 hours and 30 minutes = 2.5 hours
rate = distance/time
rate = 226 mi/2.5 hr
rate = 90.4 mi/hr
The train travels at 123.7 km/h
3 hours 15 minutes.
In 6 hours @ 120 km per hour, the train travels 120*6 = 720 km. In 5 hours @ 100 km per hour, the train travels 100*5 = 500 km. So, in all the train travels 720 + 500 = 1220 km in 6 + 5 = 11 hours. Its average speed is 1220/11 =110.9090.. recurring km per hour.
Average speed = Total Distance/Total Time = 350/3 = 116.66... km per hour.

Hints: speed = (distance) / (time) You need to convert 1 hour + 45 minutes into a single unit, such as hours or minutes.

Suppose the distance is D. Then, Fritz takes 36 minutes = 36/60 hours so Fritz travels at D*60/36 = 5D/3 mph. Then the train travels at 5D/3 + 48 mph So the train takes D/(5D/3 + 48) hours = 20 minutes Therefore D/(5D/3 + 48) = 1/3 D = 1/3*(5D/3 + 48) 3D = (5D/3 + 48) 9D = 5D + 144 4D = 144 So D = 36 miles
1.4:1 in favor of the train.

The Eurostar travels between London and Paris, and between London and Brussels. It does not travel between Paris and Geneva.
This is an average speed of 42.54 km/h
3 hrs & 34 minutes is the same as 3.56666666666 hours. Divide this into 90 km and your answer is 25.233645 km/h (average)
