A plane takes off from an aiport and flies east at a speed of 350 mi/h. Ten minutes later, a second plane takes off from the same airport and flies east at a higher altitude at a speed of 400 mi/h. How long does it take the second plane to overtake the first plane?

I have tried to figure this out but it is hard when the teacher didn't teach it to you and tells you "do your best"
Help would be appreciated so much!

IT requires thinking. They flew the same distance, one had a ten min heard start.

distance1=350*t t in hrs
distance2=400(t-10/60)

set them equal, solve for t. Then, the second plane must fly t-10/60 hr
thanks. i had that but instead of subtracting i was adding for some reason.
a=6,b=8
3*4
