d
How long would it take for that train to cover 100 miles?

Answer 1

x = 1 2/3 hours

Explanation:

We can use ratios to solve

150 miles 100 miles

---------------- = ---------------

2.5 hours x hours

Using cross products

150x = 2.5*100

divide each side by 150

150x/150 = 250/150

x = 1 2/3 hours
