Will ran 3.23 km the first week and 4.15 km the second week. Chuck ran 8.75 km in two weeks.

Round each distance Will and Chuck ran to the nearest tenth of a kilometer. Then estimate.

About how much farther did Chuck run than Will?

A.
about 1.1 km

B.
about 1.2 km

C.
about 1.3 km

D.
about 1.4 km

Respuesta :

Will ran 3.23 + 4.15 = 7.38 in those 2 weeks, which rounds up to 7.4 km.
Chuck ran 8.75, which rounds to 8.8.

8.8 - 7.4 = 1.4 km
This means that Chuck ran 1.4 km more than Will, therefore the answer is D. about 1.4 km.

Hope this helps :)

The first step is to add both of Will's runs together, then you will round to the nearest tenth (tenth is the first place after the decimal) and then look at you r results, from there you can answer the question
