Answer:
1.C. 88 lbs
2. D. 1 hour 30 minutes
3.A. 100mm
4.C. (100 x 9)/5 + 32 = 212F
5.A. 5,600m
6.A. 105.8°F
Step-by-step explanation:
1.Just multiply Angela's weight 40kg to 2.2 pounds, and that's it.
2. 3 times 30 is equal to 90 minutes
3. In order to answer this question, you'll need to look closely first at the unit of measurements provided in the problem. It says here that the shoe box is 20 cm long and 10 cm wide, the unit of measurement in the given is in centimeters.
2. Your answer should be in millimeters, a different unit of measurement from the given.
3. You'll have to convert the given length and width into the desired unit measurement, then you can proceed to performing the operation needed.
See this conversion system:
1 centimeter = 10 millimeter
4. Knowing this in mind, you'll need to multiply how many centimeters the given is to 10 in order to convert it in millimeters.
length= 20 cm
20 x 10 = 200
=200 mm
width= 10 cm
10 x 10 = 100
= 100 mm
5. to know which one is longer, you'll need to do some subtraction. Subtract the width from the length to know how many millimeters longer is the length than the width.
200 mm - 100 mm = 100 mm.
5.Let the distance of his office be xkm and thr right time to reach office be t min
Time taken to reach office at 8km/hr =60t+2.5=8x (i)
Time taken to reach office at 10km/hr =60x−5=10x (ii)
Subtracting (ii) from (i) we get,
607.5=8x−10x
607.5=405x−4x
x=607.5×40
x=5km
