To find the distance Jordan jumped recorded to the nearest tenth, we need to look at the number in the hundredths place (the second digit after the decimal point). In the number 2.86, the tenths place is 8 and the hundredths place is 6.
Since the value in the hundredths place (6) is 5 or greater, we round up the tenths place (8) by 1.
So, rounding 2.86 to the nearest tenth gives us 2.9.
Therefore, the correct answer is B. 2.90 meters.
