Question

walkin at a speed of 14 km/hr ashely takes 30 minutes to walk from home to school. how far is the school from her home.
​

Answer 1

Answer:

Walking at a speed of 14km/h

convert it into m/s (metre per second)

Converting km/h to m/s by multiplying with 5/18

14×5/18=35/9

thus,35/9 m/s is her speed

She takes 30 minutes to walk from School to her home

that is 30 mins = 1800 sec (30×60)

for finding distance, we've to use the converse of the formula ,we know speed= distance/time

thus, distance=time/speed

distance=1800/(35/9)

that is distance= 462.85 metre, taking 463 as approx value

Convert it into km

we know 1 km= 1000 m

therefore the answer in km is 463/1000 km

hope it helps

Answer 2

answer is 7 km
