Steve is trying to make the weight for a Boxing match. Steve needs to be 72kg or
less for fight night. He is currently 79kg. His trainer tells him he can lose 4lbs a week
comfortably.
Given 1kg = 2.2lbs find how many weeks it will take Steve to reach his target weight
of 72kg. Give your answer to the nearest week. You must show all of your workings
He needs to lose 7 kg or 15.4 pounds
15.4 / 4 = ________ weeks
To find out how many weeks it will take for Steve to reach his target weight of 72kg, we need to first convert the weight from kg to lbs, and then determine how many weeks it will take for Steve to lose the necessary amount of weight.
1 kg is equal to approximately 2.2 lbs, so we can use this conversion factor to convert the weight from kg to lbs.
Steve's current weight is 79kg. To convert this to lbs, we multiply 79kg by 2.2:
79 kg * 2.2 lbs/kg = 173.8 lbs
Now, we need to determine how many pounds Steve needs to lose in order to reach his target weight of 72kg. Again, we can convert the target weight from kg to lbs:
72 kg * 2.2 lbs/kg = 158.4 lbs
The difference between Steve's current weight and his target weight is:
173.8 lbs - 158.4 lbs = 15.4 lbs
Now, we know that Steve's trainer has told him he can lose 4 lbs per week comfortably. So, to calculate the number of weeks it will take for Steve to reach his target weight, we divide the total weight he needs to lose by the amount he can lose per week:
15.4 lbs ÷ 4 lbs/week = 3.85 weeks
Rounded to the nearest week, it will take Steve approximately 4 weeks to reach his target weight of 72kg.
