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 3

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 4

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 5

that is the answer : )
