Bill runs 400 meters to Andy's house, turns around, and runs 400 meters back home. what was bill displacement?

speed = distance/time

= 400/267

= 1.49

1.5

i hope this is right lol  good luck

54.864 meters

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:
