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. Use complete sentenc

First you have to convert all the speed in the same unit..
its entirely up to you to decide..
lets just convert speed of SBT train in Japan to m/sec
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
(did that help )

(in better words)
Ellen's train must be at speed (200.1 + 198.8)/2 = 199.5 mi / hr to be the second fastest train.

In 2.5 hours the train will travel: 199.5 x 2.5 = 499 miles.
