Answer:
heres the equation in order for t which is time it takes for james to reach his home
3/15=5/t to solve for t multiply both sides by it
3/15t=5 now the decimal value for 3/15 is 0.2
so,
0.2t=5 now divide both sides by 0.2 to isolate t by itself hence the time it takes for james to reach home is t= 25 minutes
