Multiple 18% by 600 and then multiply the number you get from that by 24 and add that number onto 600 and that’s your answer
Given :
Distance covered by object , D = 63 cm .
Time taken to cover distance D , t = 2 days .
To Find :
The speed of object in m/s .
Solution :
First we will convert all units into m and hours .
D = 63 cm = 0.63 m .
.
Now , speed is :

Hence , this is the required solution .
2(5-n)=-2+(-1*n)
2(5-n)=-n-2
distribute
10-2n=-n-2
add 2n to both sides
10=n-2
add 2 to both sides
12=n
