Question

Two trains going in opposite directions leave at the same time. train b travels 2020 mph faster than train

a. in 88 hours the trains are 960960 miles apart. find the speed of each.

Answer 1

I'm assuming a typo here, where all of the figures are typed twice. So let the speeds of the trains be n and n+20. Then:
8n+8(n+20)=960
16n=800
n=50
n+20=70
