Question

Dinesh takes 20 minutes to cover a distance of 5 km on a bicycle calculate his average speed in kilometers/hours

Answer 1

Answer:

Step-by-step explanation:

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

Given:−

→ Distance ( d ) = 5 km

→ Time taken ( t ) = 20 min

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

ToFind:−

→ Speed = \huge\bold\purple{ ? }?

We know that

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

TotalTime

TotalDistance

❤ Average Speed = \frac{ 5 }{ 20 }

20

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

Answer 2

Answer:

Average speed in kilometers/hours = 15km/h

Explanation:

Given,

Distance covered by Dinesh = 5km

Time taken to travel 5km = 20minutes

To find,

The average speed in kilometers/hours

Recall the formula,

Average speed = $\frac{Total\ distance \ traveled}{Total \ time \ taken}$

60minutes = 1 hour

Solution:

Since 60minutes = 1 hour,

1 minute = $\frac{1}{60} hour$

20 minutes = 20× $\frac{1}{60} hour$

= $\frac{1}{3}$ hour

Hence, time taken to travel 5km = 20min = = $\frac{1}{3}$ hour

Average speed =  $\frac{Total\ distance \ traveled}{Total \ time \ taken}$ = $\frac{5}{\frac{1}{3} }$ = 15km/hour

Answer:

Average speed in kilometers/hours = 15km/h
