Ben and jack took part in a cycle race ben took 47 minutes 39 seconds and jack took 54 minutes 12 seconds to complete the race what is the difference between the two times

Jack took 6 minutes and 33 seconds longer to complete the race.

Step-by-step explanation:

54 minutes minus 47 minutes would equal 7 minutes longer, but Jack was not as far into the minute when he completed it as Ben was when he completed it, so the difference in time is actually going to be a bit less than 7 minutes. So the difference is going to be 6 minutes and the number of seconds between 39 and 12, with 39 going past the minute, that is. That equals out to 33 seconds, so the total difference in time is 6 minutes and 33 seconds.

14

step-by-step explanation:

14 x 3 = 42

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
