Question

WILL GIVE MEDAL!!!

3.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

Answer 1

@aryandecoolest

Answer 2

convert speed of TGV in km/hr...

Answer 3

And how would i do that ?

Answer 4

multiply the speed with 18/5 to get it into km/hr

Answer 5

321.984 ?

Answer 6

what happened?? you will get it as 31.98 km/hr...
after see the speed should be between 321.98km/hr and 320km/hr
so speed for the new design may be 321 km/hr...

Answer 7

Darn i got the wrong answer lol , so 321 km/hr would be my final answer ?

Answer 8

yep!! shld be....The speed will be 199.50 m.p h.
and the distance running at a constant speed will be
199.5 X 2.5 = 498.75 miles~499miles

4.Beatriz is creating graphs for her city’s Parks Department. Beatriz is trying to persuade the Parks Department to put in more gazebos for shade. For a local park, Beatriz wants to demonstrate the attendance as it changes every week. She also wants to show the temperature changes per month. Sometimes temperatures reach below zero. Explain to Beatriz how to make the graphs correctly based on the data that she will collect and what labels, scales, and intervals each axis must have on each graph.
