Question

calculate the speed of a vehicle that travelled 75 km in 2 hours. Express the speed in both km per h and m per s.​

Answer 1

Answer:

37.5km/h and 1250m/s

Step-by-step explanation:

speed = distance/time

75/2= 37.5 km/h

and

75000/60 = 1250m/s

Answer 2

Answer:

10.41 m/s

Step-by-step explanation:

D= 75

T = 2h

S= D/T

75÷2=37.5 km/h

to convert km per hour m/s multiple by 5/18

therefore, 37.5× 5/ 18

75/2 × 5/18

10.41 m/s
