The two #'s are 156 and 4.
When you multiply 156*4=624.
When you add them together 156+4=160
You can also check you're work using a calculator.
I think you would have 3 1/2 yards left (3 2/4 simplified)
Hi there!
In order to find your answer, you'll need to use the cross product method :
150 miles → 2 1/2 hours = 150 minutes
x miles → 3 hours = 180 minutes
(150 × 180) ÷ 150 = x miles
27,000 ÷ 150 = x miles
180 = x miles
Your answer is: A train would cover 180 miles in 3 hours.
There you go! I really hope this helped, if there's anything just let me know! :)
