Question

if the distance covered by a car moving with speed of 500m/s is 5km then the time of travel is given by​

Answer 1

Step-by-step explanation:

1. Distance = Speed × Time

2. 1 km/hr =

5

18

m/s

3. If the ratios of speed is a : b : c, then the ratios of time taken is :

1

a

:

1

b

:

1

c

Relation between variables:

To distance, Speed and Time both are directly proportional and To speed, Time is inversely proportional.

S

∝

D

and

T

∝

D

i.e. if speed is doubled, distance covered in a given time also gets doubled and ,

S

∝

1

T

i.e. if speed is doubled, time taken to cover a distance will be half.

Average speed is defined as =.

Answer 2

Answer:

10 seconds

Step-by-step explanation:

given that,

if the distance covered by a car moving with speed of 500m/s

so,

speed = 500 m/s

distance = 5 km

= 5000 m

time taken = distance/speed

= 5000/500

= 10 s

so,

time taken = 10 s
