Tara ran to the park and then walked to the store. She ran 4 times as long as she walked. The total time spent walking and running was 25 minutes. Write an equation that can be used to solve for how long it took Tara to walk from the park to the store?
A= x + 4 = 25
B= 1/4x = 25
C= 1/4x + x = 25
D= x + 4x = 25
