<span>How fast (in miles per hour) did he drive the first 3 hours? "He drove 56mph the first 3 hours."
Explain how you got your answer. "I got my answer by divding the miles he drove (168) by how many hours it took (3) to get 56."
If he continues to drive at that rate, how many hours will it take him to go the 280 more miles? "It will take him 5 more hours."
Explain how you got your answer. "I divided the miles he needs to travel (280) by the mph he would be going (56)."</span>
100 cm = 1 meter
210 cm = 2.1 meters (multiply both sides by 2.1)
Mary uses 2.1 meters of thread so far, meaning she has 10-2.1 = 7.9 meters left
7.9 meters = (7.9 m)*(100 cm/1 m) = 790 cm
--------------------------------------
Alternate route:
10 meters = (10 m)*(100 cm/1 m) = 1000 cm
Mary uses 210 cm out of 1000 cm total, so she has 1000-210 = 790 cm left.
--------------------------------------
<h3>Answer: 790 cm</h3>
<span>E = {x|x is a perfect square between 1 and 9} = {1,4
</span><span>F = {x|x is an even number greater than or equal to 2 and less than 9}
</span><span>D = {x|x is a whole number}
</span>
answer
D ∩ (E ∩ F) = 4
