Louis has already biked 4 1/2 miles this week. He can bike 8/6 miles in one hour. Let the total distance biked be represented by d. Let the number of hours biking be represented by h. An equation that represents this scenario is: d=8/6h+4 1/2
what is the total number of miles if he bikes 21 hours?
answer as a decimal

Respuesta :

Replace h in the equation with 21 hours and solve for d:

D = 8/6(21) + 4 1/2

D = 28 + 4 1/2

D = 32 1/2

As a decimal: 32.5
