280

Answer 1

The second car traveled 280 miles farther than the first car.

Explanation:

Car A: 50 mi/1 hr for 4 hrs

Car B: 60 mi/1 hr for 8 hrs

Solve for Car A:

50 mi/1 hr × 4 hrs

50 × 4

200 miles

Solve for Car B:

60 mi/1 hr × 8 hrs

60 × 8

480 miles

Find the difference between Car A and Car B:

480 miles - 200 miles

280 miles
