The answer is D, none of these
Answer:
The distance cover by him walking back is 11.25 miles
Step-by-step explanation:
Given as :
Time for Janelle to spend on training = 5 hours
The running speed of Janelle = 9 mph
The walking back with 3 mph
Let The distance for running and walking is same i.e D miles
SO, Time = 
∴ 5 = 
+ 
Or, 5 × 9 = D + 3 D
Or, 45 = 4 D
∴ D = 
= 11.25 miles
Hence The distance cover by him walking back is 11.25 miles Answer
Answer:
10 minutes
Step-by-step explanation:
To solve this , we need to first calculate the volume of the rectangular prism. Let’s say this is V.
Mathematically, V = w h l where w, h and l are width , height and length respectively.
V = 20 * 18 * 10 = 3600 in^3
Now to get the number of minutes, we divide the volume by the draining rate.
That would be 3600/360 = 10 minutes
Answer:
56
Step-by-step explanation:
Divide 280 by 4/5 and get 14 then multiply by 4 and get 56
Answer:
11309.7 cm
Step-by-step explanation:
Volume = πr^2h
= π×20^2×9
= 3600π
= 11309.733552923
=11309.7 cm
