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 Sam's rate as stated?

Sam's speed is about 10.3 mi/h.

Step-by-step explanation:

Sam's speed is about 10.3 mi/h.

Explanation:

Use dimensional analysis.

Determine the equality between miles and feet, and hours and minutes.

1 mi=5280 ft

1 h=60 m

Each equality can make two conversion factors, which are equal to one.

1 mi

5280 ft

=

1

=

5280 ft

1 h

60 min

60 min

1 h

Multiply the given value by the conversion factor that has the desired unit in the numerator. This will leave you with the desired unit, and the undesired unit in the denominator will cancel.

Convert feet to miles.

step-by-step explanation:

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)
