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

Bullet Train = 320 km / hour

TGV train = 89.44 meters / second = 89.44 X 3600 meters / hour = 89.44 X 3600 /1000 km/ hour

= 89.44 X 3.6 = 321.984 km/ hour

TGV train is faster

Ellen's train has to go faster than 320 km/ hour but less than 321.984 km/ hour i.e around 321 km/ hour to be the second fastest train ANSWER

Distance in 2.5 hours = 321 X 2.5 = 802.5 km

Answer 2

its so easy see and follow this method

Answer 3

Bullet Train = 320 km / hour

TGV train = 89.44 meters / second = 89.44 X 3600 meters / hour = 89.44 X 3600 /1000 km/ hour

= 89.44 X 3.6 = 321.984 km/ hour

TGV train is faster

Ellen's train has to go faster than 320 km/ hour but less than 321.984 km/ hour i.e around 321 km/ hour to be the second fastest train ANSWER

Distance in 2.5 hours = 321 X 2.5 = 802.5 km

Answer 4

oh ok
