Answer:
84 calories
Step-by-step explanation:
A rock climber burns 60 calories for every 5 minutes of rock climbing.
Find the amount of calories burned every minute by dividing 60 with 5:
60/5 = 12/1
For every minute climbed, the rock climber burns ~12 calories.
Now, you are trying to find how many calories are burnt in 7 minutes. To do so, multiply 7 with 12:
12 x 7 = 84
84 calories are burnt in 7 minutes of rock climbing.
