2. A sugar-free powdered drink mix sells for $2.99 per can. Each can of the mix
contains 50.2 g of powder, which, when added to water, will make 8 quarts of
drink. What is the cost of the powdered drink mix in dollars/lb? (454 g = 1 lb)

A car is travelling at 60 miles per hour. Express this speed in kilometers per hour

Answer 1

To find the cost of the powdered drink mix in dollars/lb, we need to convert the given weight of the mix from grams to pounds.

1 lb = 454 g

Therefore, the weight of the mix in pounds is:

50.2 g * (1 lb / 454 g) = 0.11 lb

Now, let's find the cost per pound:

Cost per pound = Cost per can / Weight per can
= $2.99 / 0.11 lb
= $27.18/lb

So, the cost of the powdered drink mix in dollars/lb is $27.18.

Moving on to the second question, to convert miles per hour to kilometers per hour, we need to use the conversion factor:

1 mile = 1.60934 kilometers

Therefore, the car's speed in kilometers per hour is:

60 miles/hour * 1.60934 kilometers/mile = 96.56 kilometers/hour

So, the car is traveling at a speed of 96.56 kilometers per hour.
