Mr. Verma drives his car at uniform speed from bottom of a mountain to the top in `30` minutes along a helical path as shown.
At the beginning the speedometer of his car shows `6225 km`, while on reaching the top it reads `6285 km`. (Take upward as positive y-axis and positive x-axis towards right) The total distance covered is.

A

30 km

B

20 km

C

60 km

D

cannot be determined

Text Solution

Verified by Experts

The correct Answer is:
C
Total distance covered = Final reading - Initial reading `=6285 - 6225 = 60 km`.

Two highways are perpendicular to each other : imagine them to be along the x-axis and the y-axis, respectively. At the instant t=0, a police car P is at a distance d= 400m from the intersection and moving at speed of 80km // h towards it along the x-axis. Motorist M is at a distance of 600m from the intersection and moving towards it at a speed of 60km // h along the y-axis . The minimum distance between the cars is

A naughty bird is sitting on top of a car. It sees another car approaching it at a distance of 12 km. The speed of the two cars is 60 km/hr each. The bird starts flying from the first car and moves towards the second car, reaches the second car and comes back to the first car and so on. If the speed at which the bird flies is 120 km/hr. The total distance travelled by the bird. (Assume that the two cars have a crash)
