Answer:
48 miles
Explanation:
On Monday, Elliot rode 6 miles on a bike. On Tuesday, he rode 6 miles. On Wednesday, he rode 3 times farther than he did Monday and Tuesday combined.
How many miles has Elliot ridden so far this week?
This is calculated as:
Number of miles he rode on Monday + Number of miles he rode on Tuesday + Number of miles he rode on Wednesday
= 6 miles + 6 miles + 3(6 + 6)miles
= 12 miles + 3(12 miles)
= 12 miles + 36 miles
= 48 miles
Therefore, Elliot has ridden 48 miles so far
