It covers 150 m in 5 seconds.
a. Calculate its average speed?
b. Calculate the distance covered by it in 1 second.
c. Calculate the distance covered by it in 10 second.
d. How much time does it take to cover 240 m distance?
e. How much time does it take to cover 100 m distance?

Please help!!

Answer 1

Answer:

Explanation:

(a)Average speed of the car will be the total distance traveled in the total time.  

Average speed = $\frac{Total distance }{total time}$

Taking distance travelled as 150 in 5 seconds we have average speed as.  

Average speed = 150/5 = 30 $\frac{m}{s}$

(b)   Distance traveled in t = 1 sec. is the product of speed and time, thus we have  

Distance=speed×time  

30×1=30 m.

(c)  Distance traveled in t = 6 sec is the product of speed and time in that interval. thus  

Distance  =180 m.

(d)  Time taken to travel 240 m is the distance traveled with a particular speed in that interval.

t= $\frac{distance }{ time}$

 = $\frac{240}{30}$

 = 8sec
