Ellen works for a high-speed rail company that wants to develop a new rail line. Ellen’s project is to find a train that is the second fastest in the world. The Shinkansen Bullet Train in Japan is reported to go as fast as 320 kilometers per hour. The TGV train in France can reach speeds of 89.44 meters per second. Explain to Ellen how to find what speed her new train must go to be the second fastest in this group. Then, find an appropriate speed for Ellen’s train in miles per hour and use the formula distance = speed • time to find how far the train can go in 2.5 hours. Use complete sentences and show your work.

The easiest way is to convert all speeds to MPH

 Japanese train moves at 320 km/h

1mi/h = 1.6093km/h or 1 km/h = 1/1.6093 mi/h

Then

320 km/hr = (320km/h)/(1.6093km/h) = 198.8 mi/hr 

French train moves at 89.44 meters per second.

Convert to meters per hour by multiplying by (3600s/1h) (89.44m/s) = 321984 meters / hour

Convert meters to km by multiplying by (1km/1000m) (321984m) = 321.984 km/hr (then restore the rate)

Convert Km to miles by multiplying by (1mi/1.6093km) (321.984km) = 200.1 mi/hr (then restore the rate)

The fastest train is the French train at 200.1 mph

The Japanese train is at 198.8 mph

To have the second fastest train, the speed has to be between these two numbers.

Ellen’s train need to be 198.8mph < E < 200.1mph (E=Ellen’s train)

The hardest part was using complete sentences. Guys don’t speak in full sentences. We use short phrases and then grunt. Or we use sign language. Usually a certain finger. I guess it’s a kind of digital language.

The easiest way is to convert all speeds to MPH

 Japanese train moves at 320 km/h

1mi/h = 1.6093km/h or 1 km/h = 1/1.6093 mi/h

Then

320 km/hr = (320km/h)/(1.6093km/h) = 198.8 mi/hr 

French train moves at 89.44 meters per second.

Convert to meters per hour by multiplying by (3600s/1h) (89.44m/s) = 321984 meters / hour

Convert meters to km by multiplying by (1km/1000m) (321984m) = 321.984 km/hr (then restore the rate)

Convert Km to miles by multiplying by (1mi/1.6093km) (321.984km) = 200.1 mi/hr (then restore the rate)

The fastest train is the French train at 200.1 mph

The Japanese train is at 198.8 mph

To have the second fastest train, the speed has to be between these two numbers.

Ellen’s train need to be 198.8mph < E < 200.1mph (E=Ellen’s train)

Hi mari379,

You should be honored. It’s not every new member that gets a special episode of “Moonlight at the Taj Mahal” staring Rosala and Zergroes.

This is a continuing saga. It is very dramatic and entertaining, with the two best stars and a great cast of extras.

(We learn more than math here!)

Zegroes needs a helper! It’s all he can do to keep up with you. --I mean keep 10 or 20 steps within your range of wit. How did you ever learn to do that?

Learn to communicate in a funny (witty) manner – for you it is a natural gift, but to be that good at it requires practice.

Zegreos is funny too, but the two of you together makes it really funny and entertaining.
