Jumping rope can burn 600 calories per hour. Write and solve an inequality to find the number of hours jumping rope that it would take for you to burn at least 450 calories.

X is the number of hours to burn 450 calories:
equality method:
600 calories * 1 hour  = 450 calories * x hours
x hours = 450/600 calories * 1 hour 
x = 0.75 
So, she needs 0.75 hours (45 minutes) to burn 450 calories

Inequality method:
600x > 450
x > 450/600
x > 0.75
So, she needs at least 0.75 (45 minutes) to burn at least 450 calories.

Hope this Helps! :D
