Answer:

1. The distances are accurate.

2. 57 miles

Step-by-step explanation:

Quiz 1 solution

1 mile = 1.60934 km

10 miles will be;

10 × 1.60934 = 16.0934 km

Distance on the sign is 16 km.

The distance is accurate since 16.0934 km rounded up to nearest kilometre is equal to 16 km.

13 miles will be;

13 × 1.60934 = 20.92142 km

The distance on the sign is 21 km

This distance is accurate since 20.92142 km rounded up to nearest kilometre equals 21 km

55 miles will be;

55 × 1.60934 = 88.5137 km

The distance on the sign is 89 km

The distance is accurate since 88.5137 km rounded up to nearest kilometre is 89 km.

Quiz 2 solution

1 km = 0.621371 miles

92 km will be;

92 × 0.621371 = 57.166132 miles

Rounding up the answer to nearest mile gives 57 miles.
