Answer:
187.5 m^3
Step-by-step explanation:
2 to 5 is 2(2.5)
2.5^2 = 6.25
6.25(30) = 187.5
Answer:
B) 20.6 mi/hr
Step-by-step explanation:
To solve this, we need to first convert 40 meters to mile, then convert 4.35 seconds to hour, then solve by proportion.
converting 40 meters to mile;
1 mile = 1609.344 meter
x = 40 meters
1609.344x = 40
x = 40/1609.344
x =0.02485 mile
Then converting seconds to hour
1 hour = 3600 seconds
y = 4.35 seconds
3600 y = 4.35
y=4.35/3600
y =0.00121 hour
Using proportion to solve the question
Let n be the number he runs miles per hour
0.02485 mile = 0.00121 hour
n = 1 hour
cross-multiply
0.00121 n = 0.02485
Divide both-side by 0.00121
0.00121 n/0.00121 = 0.02485/0.00121
n ≈ 20.6 mile/hour
Therefore, he is running 20.6 mi/hr
