Solution

The correct option is A

$Average speed of the cab = \frac{d i s t a n c e t r a v e l l e d}{t i m e t a k e n}$

$= \frac{(difference in odometer readings)}{t i m e t a k e n} = (\frac{100}{2}) k m / h r = (\frac{50 \times 5}{18}) m / s = 13.9 m / s$

The initial odometer reading of a cab is 369 km. It travelled for 2 hours and the final odometer reading showed 469 km. Find the approximate averge speed of the cab.

The correct option is A Average speed of the cab=distance travelledtime taken =(difference in odometer readings)time taken=(1002)km/hr=(50×518)m/s= 13.9m/s

The correct option is A

$Average speed of the cab = \frac{d i s t a n c e t r a v e l l e d}{t i m e t a k e n}$

$= \frac{(difference in odometer readings)}{t i m e t a k e n} = (\frac{100}{2}) k m / h r = (\frac{50 \times 5}{18}) m / s = 13.9 m / s$
