How long to drive 278 miles at 70 miles per hour?

Answer 1

These types of questions can be solved with a simple formula, which is actually interchangeable when you need to find distance, speed, and time.

T = D/S

S = D/T

D = S/T

So based on the T = D/S formula we get:

278 miles ÷ 70 miles/hr = 3.97 hours
