Step-by-step explanation:
[tex] \frac{80}{1} + \frac{3}{4} \\ \frac{80 \times 4 + 3 \times 1}{4} \\ \frac{320 + 3}{4} = \frac{323}{4} \\ \frac{323}{4} \times \frac{16}{10} \\ = \frac{5168}{40} = 5168 \div 40 = 129.2[/tex]
First of all... convert every number in fraction n/1 and then find how many kilometres are between (+). Then you multiply by 1.6 (16/10 in fraction) to find how many miles are there. And then (optional) I converted back to whole number. There are 129.2 miles between the towns.
