Question

A hot air balloon is at an altitude of 10015 yards. The balloon's altitude decreases by 1045 yards every minute. Which equation can be used to determine the number of minutes m it will take the balloon to reach an altitude of 57 yards?

Answer 1

Answer:

9.53 minutes

Step-by-step explanation:

Given:

Initial altitude = 10015

Rate of decrease per minute = slope = 1045

Number of minutes, m it will take the Ballon to reach altitude of 57 = final altitude

The Given could be modeled into an equation thus :

Initial altitude - (rate * Number of minutes) = final altitude

10015 - (1045 * m) = 57

10015 - 1045m = 57

-1045m = 57 - 10015

-1045m = - 9958

m = 9958 / 1045

m = 9.529186

m = 9.53 minutes
