Question

Complete the rate table. Enter fractional answers as decimals.Distance (km)0.4Time (min)510202560

Answer 1

Distance (km) 0.4 0.8 1.6 2 4.8

Time (min) 5 10 20 25 60

Step-by-step explanation:

This is a direct relation, it means that when the time increase, the distance increase. So, the ratio of the distance to the time is constant, then we can calculate the distance for 10 min as follows

`10\text{ min}*\frac{0.4\text{ km}}{5\text{ min}}=\frac{10\text{ min}*0.4\text{ km}}{5\text{ min}}=0.8\text{ km}`

In the same way, we get the following for 20, 25, and 60 min

`20\text{ min}*\frac{0.4\text{ km}}{5\text{ min}}=\frac{20\text{ min }*0.4\text{ km}}{5\text{ min}}=1.6\text{ km}`
`25\text{ min }*\frac{0.4\text{ km}}{5\text{ min}}=\frac{25\text{ min }*0.4\text{ km}}{5\text{ min}}=2\text{ km}`
`60\text{ min}*\frac{0.4\text{ km}}{5\text{ min}}=\frac{60\text{ min }*0.4\text{ km}}{5\text{ min}}=4.8\text{ km}`

Therefore, the complete table is

Distance (km) 0.4 0.8 1.6 2 4.8

Time (min) 5 10 20 25 60
