Question

9) A car travels 100 m in 10 s. What is the average speed?
a. 36 Km/h
b. 10 Km/h
c. 0.1 s/m

Answer 1

Answer:

option A is correct 36km/hrs

Explanation:

DISTANCE CAR TRAVEL=100M

TIME=10SEC

AVERAGE SPEED =

$\frac{total \: distance \: \: }{total \: time} = \frac{100m}{10sec} = 10m |sec$

1m=1/1000km

1sec=1/3600hrs

10×1/1000×3600=36km/hrs
