jim began a 183 mile bicycle trip to build up stamina for a triathlete competition. unfortunately his bicycle chain broke so he finished walking. the whole trip took 7 hours. if jim walks at a rate of 3 mph and rides at 39 mph, find the amount of time he spent on the bike

distance = speed * time

let 'x' represent the amount of hours Jim rode the bike, then '8-x' represents the number of hours he walked

183 = 31x+5(8-x)

Step-by-step explanation:x=5.5

8-5.5=2.5

Jim rode the bike for 5.5 hours and then walked for 2.5 hours.

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
