a rock climber burns 60 calories for every 5 minutes of rock climbing.
write a proportion on the lines below to determine how many calories a rock climber would burn in 7 minutes.
:
Write a proportion which says,"5 min is to 7 min, as 60 cal is to x cal
5%2F7 = 60%2Fx
Cross multiply
5x = 7*60
x = 420%2F5
x = 84 calories
;
We can check the solution using a different method
Cal/min = 60/5 = 12 cal, hence 7 * 12 = 84
