Question

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

Answer 1

well we first need to compare the two times, then we need to find one that is between the two and then convert that to miles!

Answer 2

so to start we need to put to two units into the same unites
it meters and kilometers so this should be easy

Answer 3

if we put them all in kilometers how much would 89.44 meters be?

Answer 4

sorry i can't give you the complete answer because it's agains the code of conduct

Answer 5

thats fine its better for me to learn it anyway thanks

Answer 6

ok so what would be 89.44 meters in kilometers?

Answer 7

so,89.44 meters into kilometers?

Answer 8

yeah here's a hint: a kilometers is 1000 meters (the word kilo means 1000)

Answer 9

oh so like 0.0894?

Answer 10

exactly

Answer 11

next: one is in second the other is in hours so let's put them both in hours

Answer 12

we have to convert 0.08944 km per second to hours

Answer 13

ok,0.024844444?

Answer 14

we can do this by multiplying it by 60 so it will be per minutes and then another time to get per hour

Answer 15

no we have to multiply

Answer 16

your answer should be in the hundreds

Answer 17

so i multiply 60 by the number?

Answer 18

use a calculator!

Answer 19

yeah and then again!

Answer 20

im probably doing it wrong cuz i got 5.364?

Answer 21

nvm thanks for the help

Answer 22

ok sorry
