1hr is 60 min so
60÷15=4
45miles×2hrs=90
45÷4=11.25
90+11.25=101.25 miles
101.25 miles÷ 25 miles per gallon= 4.05 gallons
4.05 gallons× $2.75 per gallon= $11.1375

One peach weighs 65 grams. You buy a box containing 100 peaches. If the cost of peach per kilogram is AED.10, how much you have
svetlana [45]

Given:

Weight of one peach = 65 grams

Number of peaches in a box = 100

Cost of peach per kilogram is AED.10.

To find:

How much you have to pay?

Solution:

We know that,

Total weight of box = Weight of one peach × Number of peaches in a box

                                 = 65 × 100

                                 = 6500 grams

1000g = 1 kg

1 g = 0.001 kg

6500 g = 6500 × 0.001 kg

             = 6.5 kg

Now,

Cost of 1 kg = AED.10

Cost of 6.5 kg = 6.5 × AED.10

                        = AED.65

Therefore, you have to pay AED. 65.
