Question 6426: I am having trouble with this question. Suppose a family starts out 50 miles from home at time t=0. They travel away from home at a constant speed of 45 miles an hour. What's the equation that tells you how far they'll be from home t hours later? ( Assume d is distance in miles.)
Answer by xcentaur(357)   (Show Source): You can put this solution on YOUR website!
time = t hours
speed=distance/time
therefore,distance=speed*time
given speed=45 miles/hour
hence,distance=(45*t)miles
but they are already 50 miles away
so we add this to the above,giving us


distance=(50+45t)=5(10+9t)miles
