Sam ran 63,756 feet in 70 minutes. What is Sam's rate in miles per hour? ( there are 5,280 feet in one mile.) what is sams rate as stated

Sam's rate = 10.35 miles per hour.

Step-by-step explanation:

Given, Distance covered by Sam = 63,756 feet

In miles, Distance =   [1  mile = 5280 feet]

Time taken = 70 minutes

In hour , time = [ 1 hour = 60 minutes]

Sam's rate =

Hence, Sam's rate = 10.35 miles per hour.

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.
