A motorcycle travels 30 miles in 45 minutes. How many miles does the motorcycle travel in 60 minutes at this rate?

90 miles

Step-by-step explanation:

1. Divide the miles by the minutes to get the average of how much miles the motorcycle travels per minute.

2. Multiply the answer you get in step 1 by 60.

=> 45 / 30 = 1.5

=> 1.5 * 60 = 90

I might be wrong but I hope this helps :’)

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:

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)
