Question

ii) Dinesh takes 20 minutes to cover a distance of 5 km on a bicycle. Calculate his aver-
age speed in m/sec? (2 M)​

Answer 1

Step-by-step explanation:

• $\huge\underline\red{ Given \: :- }$

→ Distance ( d ) = 5 km

→ Time taken ( t ) = 20 min

• $\huge\underline\red{ To \: Find \: :- }$

→ Speed = $\huge\bold\purple{ ? }$

We know that

❤ Average Speed = $\frac{ Total \: Distance }{ Total \: Time }$

❤ Average Speed = $\frac{ 5 }{ 20 }$

❤ Average Speed = $\sf\green{ 4 \: m/sec }$

Answer 2

Answer:

we need to find the average speed

answer = 4m/s

Step-by-step explanation:

average speed = total distance travelled

                                 total time taken

                          since it is metre per second and 20 is in minutes we need to convert it to seconds and so 20 becomes 1200

we need to also convert 5km to m

= 5000/1200= 4.16m/s

thats it very simp;e
