The distance Train A travels is represented by d = 80t, where d is the distance in kilometers and t is the time in hours. The distance Train B travels at various times is shown in the table. What is the rate of each train? Which train is going faster? Time (hours) Distance (km)
2 170
4 340
5 425

The rate of Train A is km per hour.

The rate of Train B is km per hour.

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho

1 1/5

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

i dont know what you want me to answer for this but im guessing 2: 11?
