Question

you start out driving from your house to an old friends house in a different town, which is 280 miles away. after an hour and a half, you have gone 105 miles. assuming your speed is constant, find a linear function d(t), which gives the distance from your house (in miles) as a function of time (in hours).

Answer 1

You would take 280-105=175 miles away and take 105 and divide that by your time 1.5 too get 70 mph
