1km=…………...mm

Using a screw gauge the diameter of a wire is found to be, 1.51 mm, 1.53mm, 1.48 mm, 1.49 mm, I.51mm, 1.54 mm. The true value of the diameter of the wire is (in mm)

Abhishek travelled 5 km. 28 m by bus, 2km. 265 m. by car and the rest 1 km. 30m. by walk. How much distance did he travel in all ?

Of the following four wires of same material which will have maximum increase in length and which will have minimum increase in length if all are under the action of same force? Arrange the wires in the descending order of increase in length i) Natural length = 0.5m, diameter = 0.5mm ii) Natural length = 1m, diameter = 1mm iii) Natural length = 1.5m, diameter = 1.5mm iv) Natural length = 2.0m, diameter = 2mm

1 km =________________ m.m's.

A man walks at a speed of 6 km/hr for 1 km and 8 km/h for the next 1km. What is his average speed of the walk of 2 km?
