Step-by-step explanation
Answer:
0.0169 km.
Step-by-step explanation:
km - kilometers (One kilometer is equal to 1000 meters.)
dkm - dekameters (One dekameter is equal to 10 meters.)
cm - centimeters (One centimeter is equal to 0.01 meters.)
mm - millimeters (One millimeter is equal to 0.1 meters.)
Used a calc to check each of the values to see if they equal 1.69m and km was the one that wasn't equal. Instead it was 16.9.
Answer:
<u>Bob and John can finish the job together in approximately 2.92 hours or 2 hours and 55 minutes</u>
Step-by-step explanation:
Let's recall that the formula for solving this kind of problems is:
T/A + T/B = 1, where T = time working together, A = the time for person A working alone, and B = the time for person B working alone.
Now, replacing with the values we have:
T/5 + T/7 = 1
35 is the Lowest Common Multiple of 5 and 7
5T + 7T = 35
12T = 35
T = 35/12
T = 2.92 (Rounding to the next hundredth) and 0.92 * 60 ≅ 55
T ≅ 2.92 hours (Around 2 two hours and 55 minutes)
