Question

Arun rides 5 km in 2 hour on his new bicycle. How much distance will he cover in 14 hours.

Answer 1

Distance in 2 hrs=5km

In 1hr=5/2 km or 2.5km

Distance in 14 hrs= 1hr distance×14

=5/2×14

=35km

Answer 2

5 km in 2 hrs

?? km in 14 hrs.

Speed is defined as Distance per unit time. From this definition we get the formula,

Speed = Distance/Time

In first case, Arun rides 5 km in 2 hr

=> Speed = 5/2 km/hr

Since speed = distance/time

=> Distance = speed × time

Now speed = 5/2 km/hr
Time = 14 hr

=> Distance = 5/2 × 14

=> Distance = 5 × 7

=> Distance = 35 km


Hence your answer = 35 km
