Sonya made a resolution to walk 2.5 kilometers a day. On Tuesday she walked 4 times around the running track at the local high school (each lap is 0.4 kilometers.) How many additional kilometers does Sonya need to walk? (HINT: this is a multi-step problem with 2 operations...)

0.9km

Step-by-step explanation:

Given that:

Sonya's resolution = walk 2.5 km daily

Total distance walked on Tuesday = 4 times around a running track

1 lap = 0.4 km

Hence, total distance by walking 4 times around track :

0.4km * 4 = 1.6km

Additional kilometers Sonya needs to walk:

2.5 - 1.6 = 0.9 km
