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 sentenc

Answer 1

89.44(meters/second)(1kilometer/1000meters)(60seconds/1min)(60min/hour)=X kilometers/hour

Answer 2

so

89.44*(1 / 1000)*(60/1)*(60/1) = speed in kilometers per hour

Answer 3

so then you know which is the fastest and which is the second fastest

Answer 4

then you need to convert that into miles per hour

Answer 5

1 kilometeter / hour = 0.62 miles/hour
