Question

if same radius his bike 3 km in 15 minutes how for will he ride in one hour​

Answer 1

Answer:

Let half of the distance travelled be d.

Time taken at the speed of 4 km/hr = (d/4)

Time taken at the speed of 5 km/hr = (d/5)

Therefore, total time = (d/4) + (d/5) = 9 hrs.

⇒ (5d + 4d)/20 = 9

⇒ 9d = 180

⇒ d = 20.

Therefore total distance = d x 2 = 40 kms

Answer 2

Answer:

12 Km

Step-by-step explanation:

In 15minutes bike cover 3Km

than,

In 1min bike cover distance = 3/15

therefore,

In 1 hour (60min) bike cover distance

= 3/15×60

= 12Km
