Question

Q2. Zara travelled in a train moving at an average speed of 120km/h and covered a distance of 40km towards East.

i. Calculate the time taken by the train to cover this distance.



ii. She further travelled for 3hours at a speed of 120km/h towards North. Calculate the distance she covered in this time.

iii. Zia was driving his truck on the super highway. His speed was recorded by the motorway camera between 6:00am to 8:30am. He covered a distance of 250km during this time. Calculate his average speed between this time duration.​

Answer 1

i. time = distance/speed

= 40/120

= 1/3 hours

ii. distance = speed × time

= 120 × 3

= 360 km

iii. average speed = total distance/ total time

= 250/2.5

= 100 km/h

for the last question, the time is 2.5 hours because 6.00 to 8.30 is 2 hours 30 minutes. so the 30 minutes you must change to hour and plus with 2. thus, u will get 2.5 hours
