Question

if the distance from your home to a shopping complex is 20 km and it takes your car one and a half hour to reach there what would be the speed of a car

Answer 1

Answer:

one and hour means 3/2

T= 3/2

d= 20 km

s=d/t

s=20/3/2

s= 40/3

s= 13.333

Explanation:

The speed is 13.333

Answer 2

Answer:

solution

given

distance =20km

change into meter

distance =20×1000=20000m

time =one and hour =1hour 30 minutes

time=60minutes +30minutes =90minutes

time is measured in second in speed

so changing into second =90minutes ×60

=5400second

now,

speed=distance/time

=20000/5400

=3.7037ms^2
