Answer:
The man covers 200 ft in 40 seconds.

A person is moving on the sidewalk from one end to the other end.
He walks 40 feet in 8 seconds.
Therefore his speed = 
= 
= 5 ft/
He covers the sidewalk distance at a rate of 5 feet every second.
To calculate the time taken to cover 200 ft,
time = 
time =
<u>time = 40 seconds</u>
Hence the man covers 200 ft in 40 seconds.
It's 25 percent as it's Aa plus Bb which gives 4 combinations and one of them is the answer. thus 1/4 equals 25percent
Yes it is because 1/4 + 1/4 =2/4 and 2/4 equals 1/2
Answer:
r≈5.36656314
Step-by-step explanation:
Since A=πr(r+
) so we get that 226.08/pi≈72 or 226.08/3.14=72 we then plug it in to get 72=r(r+
) so we get r≈5.36656314
Answer:
