Answer:
10 km / hr
Step-by-step explanation:
Speed of boat = 15 km /hr
Speed of stream = 5km /hr .
Since both are acting opposite to each other . The the resultant speed with which it travels = 15 - 5 = 10 km/hr
T= total
<span>Money spent is: </span>
48+ 1/3 (T-48) = 1/2 T
One equation for one unknown, solve:
48 + 1/3 T -1/3*48= 1/2 T
48 - 16 =1/2 T- 1/3 T
32= 1/6 T
T= 6*32
<span>T=192
</span>192-48=144 money left after watch
1/3*144=48 third of leftover, spent on pen
<span>144-48=96 left which is half of 192. </span>
