Question

if a distance of 50metre is covered in 1 minute that 90 metre in 2 minute and 130 metre in 3 minute. find the distance covered in 15 minute​

Answer 1

Answer:610m

Step-by-step explanation:

After 1 min, distance covered is 50 m

After 2 min distance covered is 90 m

In 2nd min distance covered is (90-50)=40m

After 3rd min dist covered is 130 m

Again in next 1 min dist covered is 40m

Hence in every min passes by distance covered is 40m.

Therefore,

In 15 min of time, total distance covered will be (50+14×40)m=(50+560)m=610m

Answer 2

Answer:

610 metres

Step-by-step explanation:

As 40 metres are added after every minute so 14x40 = 560 ,

1st minute was having 50 metres so 560+50=610 metres
