Question

Samuel works for a high-speed rail company that wants to develop a new rail line. Samuel’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 Samuel how to find what speed his new train must go to be the second fastest in this group. Then, find an appropriate speed for Samuel’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 sente

Answer 14

First you have to convert all the speed in the same unit..
its entirely upto you to decide..
let us convert speed of SBT train in Japan to m/sec

Answer 15

now to convert it we multiply it's speed by 1000/3600
320∗10001∗3600
m/sec.. as 1 km =1000m and 1 hr = 3600 sec

Answer 16

lets do it this way

Answer 17

89.44 meters per second needs to convert to kilometers per hour

Answer 18

so i do 1000/3600 320∗10001∗3600

Answer 19

wait im confused

Answer 20

so 89.44*60=5344.4*60=321984 that would give u meter per hour

Answer 21

now to convert meters to kilometers

Answer 22

it would be 321.984 kilometers per hour

Answer 23

so for his train to be the second fastest it would have to be in between the two numbers 321.984 and 320
so round 321.984 to 322

Answer 24

his train would have to go 321

Answer 25

and to get the second part u plug in 321 kilometers per hour
