I'm assuming your teacher wants you to calculate the speed
1/2 = 0.5
3 & 1/2 = 3 + 1/2 = 3 + 0.5 = 3.5
If a plane flies 840 miles in 3.5 hours, then,
speed = distance/time
speed = (840 mi)/(3.5 hr)
speed = (840/3.5) mph
speed = 240 mph
<h3>Answer: 240 mph</h3>
Answer:
0.0625
Step-by-step explanation:
11^-x = 1/(11^x). if that equals four, 11^x = 0.25. 0.25^2 = (11^x)^2 = 11^2x. 0.25^2 = 0.0625. Hope this helps.
