Answer:

Step-by-step explanation:

Maria's speed is 100km/(12hr and 40min)

Convert the (12hr and 40min) into a value having a single unit (hr or minutes). I'll choose hours: 12hr + (40/60)hr = 12 2/3 hr.

We can now say that Maria's speed is 100km/(12 2/3 hr), or 7.8947 km/hr.

We want to konw how long it will take to go 1600 meters (1 mile) at that speed. 1600 meters = 1.6 km

(TIme)*(Speed) = Distance

(T)*(7.8947 km/hr) = (1.600 km)/(7.8947 km/hr)

T = 0.2027 hours, or (at 60 minutes/hr) 12.16 minutes.
