Question

What is the speed of a bus that travels 250 km in 2 hr? Answer in mi/hr. Round your answer to 3 decimal places. (1 m/s = 2.23 mi/hr) *

Answer 1

Answer:

speed of a bus = 250*1000/2*3600 m/s

=34.722m/s*2.23

=77.43mi/hr

Answer 2

Answer:

Speed = Distance/Time

Distance → 250 Km

Time taken → 2 Hr

= 250/2 = 125 Km/H

To convert km/h into m/s we multiply the value with 5/18

= 125 × 5/18 = 625/18 = 34.72

Now, 1 M/s = 2.23 Miles/He

= 34.72 × 2.23 = 77.4256 or 77.43(Rounded off)
