"Two men at points R and S, 76 km,
 apart, set out at the same time to walk towards each other. The man at R
 walks uniformly at the rate of `4 1/2`
km/hr`;`
the man at S walks at the constant
 rate of `3 1/4k m//h r`
for the first at `3 3/4`
km/hr for the second hour, and so on
 in arithmetic progression. If the men meet `x`
km nearer R than S in an integral
 number of hours, then `x`
is
`4`
b. `6`
c. `8`
d. `10`"
