For this question we will use the following relations.
100 centimeters=1 meter (or 1 centimeter= 0.01 meter)
10 millimeter=1 centimeter (or 1 mm=0.1 cm)
60 minutes = 1 hour (or 1 min= hour)
Now, Jackson's speed is 1350 meters per hour. This can be converted to cm per minute as follows:
...Equation 1
Likewise, Jonah's swim speed in cm/min can be calculated as:
...Equation 2
As we can see clearly after comparing Equation 1 and Equation 2, Jonah's swim speed of 7500 cm/min is faster than that of Jackson.
Thus, option B is correct.
Answer:
7
Step-by-step explanation:
- Plug 8 in: 12 - [2 + 6 ÷ (10 - 8)]
- 10 - 8 = 2
- Plug 2 in: 12 - [2 + 6 ÷ (2)]
- 6 ÷ 2 = 3
- Plug 3 in: 12 - [2 + 3]
- 2 + 3 = 5
- Plug 5 in: 12 - 5
- 12 - 5 = 7
I hope this helps!
