From the ground, a hot-air balloon went up at a speed of 375 feet per minute for 5 minutes. it then went down at a speed of 225 feet per minute for 6 minutes. how far is the hot-air balloon above the ground?

it went up: 375 *5 = 1875 feet total

it went down: 225 *6 = 1350 feet total

1875-1350 = 525

 it is 525 feet above the ground

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
