Answer 1

Answer:

(i) 2 hours

(ii) 75 km/hr

Step-by-step explanation:

Given:

• Speed of Amit = 50 km/hr

To find:

(i) The time taken by Amit to travel 100 km.

(ii) The distance travelled by Amit in 1.5 hours.

Method to find:

(i) Time = Distance / Speed

⇒ Time = 100 km / 50 km/hr

⇒ Time = 2 hours

__________________________________________________________

(ii) Distance = Speed * Time

⇒ Distance = 50 km/hr * 1.5 hr

⇒ Distance = 75 km

Hope it helps!

Answer 2

Given : Amit can ride scooter at constant speed 50 km/hr

To Find : Draw distance time graph

Time taken to ride 100 km

Distance covered in 1.5 hrs

Solution

Distance = Speed  * time

Speed = 50 km/hr

Distance = 50 * Time

y = 50x

y = Distance in km

x = time in hrs

Time      Distance

0              0

1               50

2             100

3             150

4              200

Time taken to ride 100 km = 100/50  = 2hrs

Distance covered in 1.5 hrs = 50 * 1.5  = 75 km
