4. Kishore purchased medicines for 205.50 and a torch for 180.50 and paid

(2017)

5. How many pieces of 25 cm length can be cut out from 4 metres long cloth
​

Answer 1

4. The balance he got is 114

Answer 2

2. speed = distance

time

= 180/3 = 60km/hr

it's uniform motion as the speed is not changing.

therefore, 60= 120/x ( taking time for 120km as x)

x= 2hr

3. use the same formula as above.

distance travelled in 8hrs = 480km

speed= 480/8 = 60km/hr

distance travelled in 2hrs = 60×2 = 120km

(distance = time × speed)

to convert above values in standard units( metre and seconds)

use,

1hr= 3600seconds

1km= 1000m

for speed simply multiply it with, 5/18
