and answer respectively :

2) how many hours he spends outside his home everyday?
3) how much distance amit covered after 1 and half hour journey?
4) find after how much time amit covered a distance of 15 km?

Answer 1

Answer:

1 ) yes the auto run by amit travels at uniform speed from 8 to 12 o clock since the graph ascends uniformly

2) he spends 16 hours 30 minutes outside hus home everyday

3) 30 mins

Step-by-step explanation:

2) he goes on workand fromthe 6am tobe 10.30 pm

which means 12 hoursand from morning 6 am to evening 6pm

and 4 hours 30 mins more from 6pm to 10.30 pn

thus, total time = 12+4:30 = 16 hours 3o mins

3 ) since, the auto runsto at uniform speed and as per reading graph we found for every 1 hr travelled by amit on x- axis , he travels a distance of 30 km on y -axis

thus to calculate time for 15 kms

$30 \div 60 = 0.5 \: {mins \: for \: every \: km} \\ 0.5 \times 15 = 30min$
