Question

A scientist drops two balls A and B from the same height. Ball A falls 4 meters in the 1st second, 9 meters in the 2nd second, 14 meters in the 3rd second, and so on. Ball B falls 3.5 meters in the 1st second, 6.5 meters in the 2nd second, 9.5 meters in the 3rd second, and so on. How many meters would each ball fall in 10 seconds?
a.
A: 49; B: 30.5
c.
A: 59; B: 36.5
b.
A: 54; B: 33.5
d.
A: 85; B: 72

Answer 1

A: 49
B: 30.5

A moves in increments of 5. So add 5 until you have hit 10 times. That comes out to 49.
B moves in increments of 3. So add 3 until you hit 10 times. That comes out to 30.5.
