Answer:
A:Joy can use the height of the picnic table to determine the size of the tarp necessary
1 km = 0.621371 miles
5 km = 5 x 0.621371 = 3.106855 miles
round off as needed.
So using whole number rounding I believe the answer you should get would be 141,550 as 3217 x 44 is equals to 141,548 so the answer may be 141,550 since 50 is the closest ten number to 48, with a distance of only 2 numbers.
18 t - 18 t * 30% = 18 t - 17 * 0,3 = 18 t - 5,4 t = 12,6 t
