Question

Talia took the bus from her home to the bank and then walked back to her home along the same route. The round trip took 0.9 hours total. The bus traveled at an average speed of 40 km/h and she walked at an average speed of 5 km/h. Use the table to complete these statements.

Answer 1

Trip 1 40 0.9-x. 40(0.9-x)
Trip 2 5. x. 5x

Answer 2

Trip 1 40; 0.9-x; 40(0.9-x)

Trip 2: 5; x;5x

Step-by-step explanation:

Since this is a rate problem.

The first trip has a rate of 40km/h

Speed = distance/time

The second trip has a rate of 5km/h

If the time it took Talia to walk is x hours

And she spent a total of 0.9 hours on the journey. So she spent 0.9-x hours on the bus

Distance for the first trip = speed × time

Distance = 40× (0.9-x)= 40(0.9-x)

Distance for the second trip = 5× x= 5x
