Pus The time, t, required to drive a certain distance varies inversely with the
speed, r. If it takes 2 hours to drive the distance at 30 miles per hour, how long
will it take to drive the same distance at 50 miles per hour?

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:

the awnser is visionary

point m is on plane r
