Question

a hot air balloon decrease its altitude by 3 ft each second for 2 seconds what was the total change in altitude and

Answer 1

Let:

h1 = Initial altitude = 0ft

h2 = Final altitude = -3ft

t1 = Initial time = 0s

t2 = Final time = 2s

`change_{\text{ }}in_{\text{ }}altitude=(h2-h1)/(2-0)=(-3-0)/(2-0)=-(3)/(2)(ft)/(s)=-(1.5ft)/(s)`
