Answer:
How far should he ride on each of the four days to reach his goal?
1st day: miles
2nd day: miles
3rd day: miles
4th day: miles
Step-by-step explanation: As the problem says, is the number of miles he rides on the first day. Let's start off with that.
1st day: miles
He want to ride 1.5 times as far as he rode the day before... no 1.5 more, but 1.5 <em>times</em> as far as he rode the day before; you would multiply 1.5 with the previous day's length.
2nd day:
Then you multiply to
to get the third day's.
3rd day:
4th day:
----------------------------
Phew! Gavin wants to ride a total of 65 miles over these four days, so if Gavin added all the miles of the four days, he should get 65...
1st+2nd+3rd+4th=65
Yes! Now that we've got the hard part done... substitute 8 for ever single .
1st day: miles
2nd day: miles
3rd day: miles
4th day: miles
