Hi
1 mile = 5280 feet
at 90 mile per hour, you have 5280 *90 = 475 200 feets
an hour is 60*60 = 3600 second
so in 1 second the train travel : 475 200 /3600 = 4752 /36 = 132 feets
so in 10 seconds : 132*10 = 1320 feets.
So, we have the information:
Save $10 first month
$5 the next months
X = amount of months
Cost = 175
So, it will take 7 months.
10+15+20+25+30+35+40 = 175
