Two toy robots are having a race. Robot A can go 14 meter in 15 seconds. Robot B can go 1 meter in 50 seconds.
1) If Robot A continues at that same speed, how long will it take to go 1 meter? Remember units! _________
2) How long for Robot A to go 4 meters at that speed? Remember units! _________
Two toy robots are having a race. Robot A can go 14 meter in 15 seconds. Robot B can go 1 meter in 50 seconds.
1) If Robot A continues at that same speed, how long will it take to go 1 meter? Remember units! _________
2) How long for Robot A to go 4 meters at that speed? Remember units! _________
To find the answers to these questions, we can use the concept of speed, which is given as the distance traveled divided by the time taken.
1) For Robot A, we know that it can go 14 meters in 15 seconds.
So, we can setup a proportion to find out the time it would take for Robot A to go 1 meter:
14 meters / 15 seconds = 1 meter / x seconds
To solve this proportion, we cross-multiply:
14 * x seconds = 15 * 1 meter
Simplifying, we have:
14x = 15
Now, divide both sides by 14 to solve for x:
x = 15 / 14
Hence, Robot A would take approximately 1.07 seconds to go 1 meter at the same speed.
Therefore, the answer to question 1 is 1.07 seconds.
2) Similarly, to find out how long it would take for Robot A to go 4 meters at the same speed, we can set up another proportion:
14 meters / 15 seconds = 4 meters / y seconds
Cross-multiplying, we have:
14 * y seconds = 15 * 4 meters
Simplifying, we get:
14y = 60
Now, divide both sides by 14 to solve for y:
y = 60 / 14
Hence, Robot A would take approximately 4.28 seconds to go 4 meters at the same speed.
Therefore, the answer to question 2 is 4.28 seconds.
Posting the same question 4 times in 7 minutes does not speed up the process, it rather slows it down.
robot A:
speed of = 14 metres / 15 seconds
= (14/15) m/s
by ratios:
14 m / 15s = 1 m/ x sec
cross-multiply, the units will divide out
14x = 15
x = 15/14 seconds
It will take 15/14 seconds to go 1 metre
so to go 4 metres at that speed would take
4(15/14) seconds or 30/7 seconds
Where does the very slow robot B enter the picture?
