Question

a car travel the distance of 60 km and 40 km in first and second hour respectively. calculate its average speed in kilometre per hour​

Answer 1

Answer:

Average speed =50 km / hr

Explanation:

The distance is 60 km / hr in 1 hour.

The distance is 40 km in next hour.

Total distance travelled = 100 km

Total time taken = 2 hr

$\boxed{\sf{Average speed = \frac{total \: distance \: travelled}{total \: time \: taken} }}$

$\implies$ $\bold{Average speed = \frac{100}{2} km/hr }$

$\bold{Average speed = 50 km / hr}$

Answer 2

Explanation:

average speed =total distance travelled \total time taken

average speed =100/2 km/hr.

=50km/hr
