...what is t when d =210?

please help im desperate here...iv been studying all day help me my brain hurts!!!!!!!!!!!

Now settle down and try to understand what is being asked here. You're given the formula

d=r*t where d is the distance traveled, r is the speed and t is the time taken. In this case r=70 so the formula is

d=70*t

If you want to know what d is when t=2.5, substitute 2.5 for t to get

d=70mph*2.5hr

Can you solve for d?

For the second one you're given

210mi=70mph*t

Can you solve for t?
