Question

A horse-drawn carriage travels 47 2/3 km in 4 1/3 hours. At this rate, how many km does it travel per hour?

Answer 1

Step-by-step explanation:

$Distance = 47 \frac{2}{3} \\ = \frac{47 \times 3 + 2}{3} \\ = \frac{141 + 2}{3} \\ = \frac{143}{3} \: km \\ Time = 4 \frac{1}{3} \\ = \frac{4 \times 3 + 1}{3} \\ = \frac{12 + 1}{3} \\ = \frac{13}{3} \: hour \\ speed \: = \frac{Distance}{Time} \\ = \frac{ \frac{143}{3}}{\frac{13}{3}} \\ = \frac{143}{3} \times \frac{3}{13} = \frac{143}{13} \\ = 11 \: km \: per \: hour$
