Question

a car is moving along a straight road at a steady speed. it travels 150m in 5 second a. what is it average speed. b. how far does it travel in 1seconds? c. how far does it travel in 6 second. d. how long does it take to travel 240m.

Answer 1

Answer:

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

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

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

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

(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= $\frac{d i s t a n c e}{s p e e d}=\frac{240}{30}$ = 8sec.

Answer 2

Answer:

Explanation:

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

Average speed =  

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

Average speed =  

(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=  = 8sec.
