Question

A small kite starts 3.7meters off the ground and rises at 6.2 meters per second. A large kite starts at 20.65 meters off the ground and drops at a rate of 5.1 meters per second. After how many seconds are the kites at the same height? Write and solve an equation.

Answer 1

Answer: The kites are at the same height at 15.41s

Explanation:

Step 1

Let t represent the time in seconds.

The equation that represents when both small and large kite are at the same height is given as

3.7 + 6.2t =20.65 +5.1t

Step 2----- Solving

3.7 + 6.2t =20.65 +5.1t

Taking like terms and subtracting

6.2t-5.1t = 20.65- 3.7

1.1t =16.95

t = 16.95/1.1

t=15.41s

The kites are at the same height at 15.41s
