the distance (in miles) traveled when driving at a certain speed 𝑠s for 38 hours, then driving 11 miles/hour faster for another hour. Express the distance in terms of s.

we know from the first 38 hours we traveled 38s miles, because time*speed=distance, so then we have (s+11)*1=s+11, for the next hour. Combining into one equation, we have 39s+11=d
