Question

Mary cycles at 6 km per hour how long will she take to reach her aunt house which is 12 km away if she cycles at a speed of 4 km/hr how long would she take

Answer 1

Three hours is its answer.

Answer 2

Answer:

At speed of 6 km/hr it will take 2 hours.

At speed of 4 km/hr it will take 3 hours.

Step-by-step explanation:

Speed of Mary = 6 km/hour

Distance = 12 km

$Time =\frac{Distance}{Speed}$

$Time =\frac{12}{6}$

$Time =2$

Thus it will take 2 hours to reach her aunt house.

If the speed = 4 km/hr

$Time =\frac{12}{4}$

$Time =3$

Thus it will take 3 hours to reach her aunt house.
