​

Answer 1

Answer:

distance covered by bike in 1 hrs= speed/time

=110/10

=11km in one hour

distance covered in 120min(2hrs)=speed×time

=11×2

=22km in 120min(2hrs).

Answer 2

Answer:

The bike covers 22 km in 120 minutes.

Step-by-step explanation:

Given,a bike covers 110 km in 10 hours.

So total distance covered by the bike $= 110 \: km$

and total time taken by the bike $= 10 \: hours$

We want to find how far does the bike go in 120 minutes.

We know, 60 minutes $= 1 \: hour$

So,120 minutes $= 2 \: hours$

By Unitary method we can solve this problem.

By one example, we can understand this concept.

Cost of 1 book is 100 rupees.

So by Unitary method, cost of 5 books are

$(5 \times 100) = 500 \: rupees$

Here in 10 hours the bike cover 110 km

So by Unitary method,in 1 hour the bike cover $\frac{110}{10} = 11 \: km$

in 2 hour the bike cover $(11 \times 2) = 22 \: km$

Therefore,

The bike covers 22 km in 120 minutes.
