travelled 5 hours, Jaipur is still 20 km away. What is the distance from Delhi to
Jaipur?​

Answer 1

Answer: Q.12 length=5h

Breadth=5h-10

Q.13 The distance from Delhi to  Jaipur? = 5v+20 km

Step-by-step explanation:

Let of the box=h cm

length is 5 times the height,

length=5h

and breadth is  10 cm less than the length

Breadth=5h-10

Q.13

Speed = Distance/Time

Distance=Speed × Time

Given that Speed=v km/h

Distance covered in 5 hours,

Distance=5v km

After the bus has  travelled 5 hours, Jaipur is still 20 km away.

The distance from Delhi to  Jaipur? = 5v+20 km

Answer 2

Answer:

Answer

Length of the box = 5h cm

Breadth of the box = (5h - 10) cm

Step-by-step explanation:

We are given that a rectangular box has height h cm

Its length is 5 times the height

Length of rectangular box = 5h

We are also given that breadth is 10 cm less than the length.

Breadth = 5h-10

Hence The length and breadth of the box are 5h and  5h-10 respectively.
