Question

A bird, which is flying at a height of 310 m above ground level, descends at the rate of 10 m per minute. Find its height from the ground after 30 minutes

Answer 1

Answer:

Height from the ground is 10m

Step-by-step explanation:

Initial Height = 310

Speed of descend = 10m/min

Distance descend by the bird = Speed×Time taken

=> Distance descend by the bird = 10×30 m = 300m

Height from ground = Initial Height - Distance descend

=>Height from ground = 310 - 300 m = 10m

Answer 2

Answer:

the bird's height after 30 min is 10 m

Step-by-step explanation:

After 30 min total descends of the bird is 10 × 30 = 300 m

final height from the ground is 310 - 300 = 10 m
