On a road trip, a family drives 350 miles

per day. How many days, d, must they

travel to reach a distance of at least

400 miles?

1.14 days (approximately)

Step-by-step explanation:

Family drives 350 miles per day

Let d = days

Equation: 350d = 400

d = 400/350

d is approximately 1.14 days

If you want to answer it without decimals, you should say around 2 days since it's going to take more than one day to travel.
