Mr. and Mrs. Chin flew from New York to Tokyo, which is a distance of 6375
miles. If it took the plane 15 hours to
fly from New York to Tokyo, what was
the plane's average speed per hour?

425 miles per hour

Step-by-step explanation:

Find the speed per hour by dividing the distance by the number of hours:

6375/15

= 425

This means the plane traveled 425 miles in one hour.

So, the plane's average speed was 425 miles per hour

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
