There is no 1 1/2 for an answer...

jiteshmeghwal9 · Answer

Let the no. of hours he worked in Friday be $x$. then,

so on Saturday, he works=(x-3)
The sum of the hours is 10. so,

x+(x-3)=10

6 1/2?

anonymous · Answer

s + f = 10
s = f - 3

now sub f - 3 in for s in the first equation
f - 3 + f = 10
2f - 3 = 10
2f = 10 + 3
2f = 13
f = 13/2 = 6 1/2

now sub 6 1/2(or 6.5) in for f into the 1st equation
s + f = 10
s + 6.5 = 10
s = 10 - 6.5
s = 3.5

check...
s = f - 3
3.5 = 6.5 - 3
3.5 = 3.5 (correct)
or...
s + f = 10
3.5 + 6.5 = 10
10 = 10 (correct)

On Friday, Tom worked 6.5 hours

Mary's hours=$x$
Mark's hours=$x-2$

Since on the trip it took 10 hours. therefore,
