| 9) A car takes 6 hours to cover a particular distance at a uniform speed of 54 How long will it take to cover the same distance at a uniform speed of 34 hrs Answer:_______________ |
| 10) A car takes 2 hours to cover a particular distance at a uniform speed of 52 How long will it take to cover the same distance at a uniform speed of 35 hrs Answer:_______________ |
| 1) A car takes 2 hours to cover a particular distance at a uniform speed of 57 How long will it take to cover the same distance at a uniform speed of 40 Answer: 3 hrs SOLUTION 1 : Given:
As speed decreases, time taken increases. It is in inverse variation. So, xy = Constant 57 x 2 = 40 x a (57 x 2)/ 40 = a = a 3 hrs = a |
| 2) A car takes 4 hours to cover a particular distance at a uniform speed of 55 How long will it take to cover the same distance at a uniform speed of 37 Answer: 6 hrs SOLUTION 1 : Given:
As speed decreases, time taken increases. It is in inverse variation. So, xy = Constant 55 x 4 = 37 x a (55 x 4)/ 37 = a = a 6 hrs = a |
| 3) A car takes 6 hours to cover a particular distance at a uniform speed of 56 How long will it take to cover the same distance at a uniform speed of 30 Answer: 11 hrs SOLUTION 1 : Given:
As speed decreases, time taken increases. It is in inverse variation. So, xy = Constant 56 x 6 = 30 x a (56 x 6)/ 30 = a = a 11 hrs = a |
| 4) A car takes 5 hours to cover a particular distance at a uniform speed of 55 How long will it take to cover the same distance at a uniform speed of 35 Answer: 8 hrs SOLUTION 1 : Given:
As speed decreases, time taken increases. It is in inverse variation. So, xy = Constant 55 x 5 = 35 x a (55 x 5)/ 35 = a = a 8 hrs = a |
| 5) A car takes 5 hours to cover a particular distance at a uniform speed of 55 How long will it take to cover the same distance at a uniform speed of 40 Answer: 7 hrs SOLUTION 1 : Given:
As speed decreases, time taken increases. It is in inverse variation. So, xy = Constant 55 x 5 = 40 x a (55 x 5)/ 40 = a = a 7 hrs = a |
| 6) A car takes 2 hours to cover a particular distance at a uniform speed of 52 How long will it take to cover the same distance at a uniform speed of 39 Answer: 3 hrs SOLUTION 1 : Given:
As speed decreases, time taken increases. It is in inverse variation. So, xy = Constant 52 x 2 = 39 x a (52 x 2)/ 39 = a = a 3 hrs = a |
| 7) A car takes 4 hours to cover a particular distance at a uniform speed of 60 How long will it take to cover the same distance at a uniform speed of 40 Answer: 6 hrs SOLUTION 1 : Given:
As speed decreases, time taken increases. It is in inverse variation. So, xy = Constant 60 x 4 = 40 x a (60 x 4)/ 40 = a = a 6 hrs = a |
| 8) A car takes 6 hours to cover a particular distance at a uniform speed of 59 How long will it take to cover the same distance at a uniform speed of 34 Answer: 10 hrs SOLUTION 1 : Given:
As speed decreases, time taken increases. It is in inverse variation. So, xy = Constant 59 x 6 = 34 x a (59 x 6)/ 34 = a = a 10 hrs = a |
| 9) A car takes 6 hours to cover a particular distance at a uniform speed of 54 How long will it take to cover the same distance at a uniform speed of 34 Answer: 10 hrs SOLUTION 1 : Given:
As speed decreases, time taken increases. It is in inverse variation. So, xy = Constant 54 x 6 = 34 x a (54 x 6)/ 34 = a = a 10 hrs = a |
| 10) A car takes 2 hours to cover a particular distance at a uniform speed of 52 How long will it take to cover the same distance at a uniform speed of 35 Answer: 3 hrs SOLUTION 1 : Given:
As speed decreases, time taken increases. It is in inverse variation. So, xy = Constant 52 x 2 = 35 x a (52 x 2)/ 35 = a = a 3 hrs = a |
