Answer 1

Step-by-step explanation:

8). 5 ft² into squared Inches:

=> since 1 ft² = 144 in²

=> 5x144

=> 720 in²

9). 16 000 cm² to m²:

=> since 1 m²= 10 000 cm²

=> 16 000 ÷ 10 000

=> 1.6 m²

10). 90 km/h to m/h

=> since 1000 m= 1 km

=> 90x1000

=> 90 000 m/h

11). 30 m/s to m/min

=> since 60 s= 1 min

=> 30÷60

=> 0.5 m/min

12). 15 rpm into rps

=> since 1 min= 60 s

=> 15x60

=> 900 rps
