Question

Amira takes 9 hours 25 minutes to complete a long wall (iv) Calculate Amira's average speed, in kilometres per hour, for the whole walk. if any of can answer that would be really good please help me. ​

Answer 1

convert 9 hour 25 minutes to hours = ( 9 + 25/60 ) hours = 113/12 hour

Let distance travelled by Amira be x km

$speed = \frac{distance}{time} = \frac{ x}{ \frac{113}{12} } \\ \frac{12x}{113} km/hr$
