Question

1) Sruthi travels a distance of 1km, 4km, 7km and 8km in time 6mins, 10mins, 12mins and 15mins respectively on bicycle. What kind of motion is it? And also write the reciprocal of such motion. 1m​

Answer 1

Answer:

The motion is Circular.

Answer 2

Answer:Let half of the distance travelled be d.

Time taken at the speed of 4 km/hr = (d/4)

Time taken at the speed of 5 km/hr = (d/5)

Therefore, total time = (d/4) + (d/5) = 9 hrs.

⇒ (5d + 4d)/20 = 9

⇒ 9d = 180

⇒ d = 20.

Therefore total distance = d x 2 = 40 kms
