The answer would be A. 3 1/2.
Explanation
First find a common denominator, which would be 6. You times the top number the same amount of times you times the bottom number to get the common denominator, so now it's 1 4/6 + 1 5/6 now you add, 1+1=2, now you need to add 4 and 5 together, bc they are the top numbers of the fraction. That would be 9 so now the problem is 2 9/6, now we simplify the fraction so that it is 3 3/6 now that simplifies into 1/2 so the answer is 3 1/2

luda_lava [24]

2.5 hours. You take the total amount of kilometers and divide it by the kph (kilometers per hour), which in this case is 11. If you do that, you'll get your answer of 2.5 hours or 2 hours and 30 minutes.

The perimeter of a rectangle given the area and height.
GuDViN [60]

hello :)

so here i am assuming that 66m^2 is the area and the height is 6.3 (sorry, but the way you wrote it is a bit funny, its all good tho)

so to calculate area it is hieght multipled by width

so you have to divide 66 by 6.3, which gives you this very long number : 10.4761904762

i would personally round it to either just 10 or 10.5

so you would want to write the answer as ≈10.5

hope that helped!

i would appreciate it if you voted me as brainliest :)
