Question

Tina took 2 hours to travel of the distance between Town A and Town B at an average speed of
72 km/h. What was Tina's average speed if she took 4 hours 12 minutes to travel from Town A to lown B.​

Answer 1

Answer: 9.52m/s

Step-by-step explanation:

Time taken = 2 hrs = 7200 s

Speed = 72km/h = 20m/s

Distance = Speed × Time

Distance = 20 × 7200

Distance = 144000m

Another time taken = 4 hrs 12 mins

= 15120 s

Distance = 144000m

Average Speed = Distance/ Time

Average Speed = 144000/15120

Average Speed = 9.52m/s
