Question

Rama drove at a constant speed for 2 hours. He then stopped for an hour to do some shopping and have a rest and then drove back home driving at a constant speed. Which graph best represents the changes in the distance from home as Rama was driving (X axis - Time, Y axis - Distance)?​

Answer 1

Given : Rama drove at a constant speed for 2 hours.

He then stopped for an hour to do some shopping and have a rest and then drove back home driving at a constant speed.

To Find :

Which graph best represents the changes in the distance from home as Rama was driving (X axis - Time, Y axis - Distance)?​

Solution:

Rama drove at a constant speed for 2 hours.

Hence Distance increased for 1st two hrs

He then stopped for an hour to do some shopping

Distance remains unchanged in next 1 hr

then drove back home driving at a constant speed.

the distance from home start decreasing as he is returning ( its Distance from home , not the distance covered )

Let side top graph

Distance is decreasing with time  Hence not correct

Right side top graph

Here it shows Distance covered  for the time not distance from home

Hence not correct

Left side bottom graph

best represents the changes in the distance from home

Right side bottom graph

Distance is fix showing Ram at Rest

Hence not correct

Answer 2

Step-by-step explanation:

★Question ::-

Rama drove at a constant speed for 2 hours. He then stopped for an hour to do some shopping and have a rest and then drove back home driving at a constant speed. Which graph best represents the changes in the distance from home as Rama was driving (X axis - Time, Y axis - Distance)?

★Given ::-

Rama drove at a constant speed for 2 hours. He then stopped for an hour to do some shopping and have a rest and then drove back home driving at a constant speed.

★To Find ::-

Which graph best represents the changes in the distance from home as Rama was driving (X axis - Time, Y axis - Distance)?

★ Solution ::-

Rama drove at a constant speed of 2hrs

Hence, Distance increased of 1st 2 hours

Then he stopped for an hour to do some shopping

Distance remains unchanged in next 1hr

Then drove back to home driving constant speed

The distance from home start decreasing as he is retuning [Its distance from home, nor the distance covered ]

• Let side top graph

Distance is decreasing with time

=> Hence not correct

• Right side top graph

Here it shows Distance covered for the time not distance from home

=> Hence not correct

Left side bottom graph

Best represents the changes in the distance from home

• Right side bottom graph

Distance is fix showing Ram at rest

=> Hence not correct
