Question

Someone jumps on a trampoline. It takes her 1 second to reach the height of 2 feet. What is their speed?

a) 1 ft/s
b) 2 ft/s
c) 1/2 ft/s
d) 2/3 ft/s

Answer 1

In this case, the distance travelled is 2 feet and the time taken is 1 second. The formula for speed is speed = distance/time. Substituting the values, we get speed = 2 ft/1 s = 2 ft/s. Therefore, the speed is 2 ft/s.

Step-by-step explanation:

When someone jumps on a trampoline and reaches a height of 2 feet in 1 second, the calculation of their speed can be found by dividing the distance covered by the time taken. Here, to reach the height of 2 feet in 1 second, the speed would be 2 feet divided by 1 second which equals 2 feet per second (ft/s). So the correct answer is b) 2 ft/s.
