A car starts from P and follows the path...

A car starts from P and follows the path as shown in figure. Finally car stops at R. If the distance travelled is s and magnitude of displacement of the car is d then value of `(3s)/(4d)`.
`[a = 7m, b = 8m " and " r = (11)/(pi) m " take " pi = (22)/(7)]`

Text Solution

Verified by Experts

The correct Answer is:
1
Distance travelled by the car `= 48 m`,
Displacement of the car `= 36 m`
