Choose one or more conversion factors that can best be used to convert 50 (km)/(Myr)(kilometers per million years) to (cm)/(yr) (centimeters per year).

(100 cm)/(1 m)

(1 Myr)/(1000000yr)

(1000 m)/(1 km)

(1 km)/(1000 m)

(1min)/(60sec)

(60 min)/(1 hr)

(1hr)/(60 min)



Now convert 50 (km)/(Myr)to _______(cm)/(yr). (cm)/(yr)

1) (100 cm)/(1 m), (1000 m)/(1 km), (1 Myr)/(1000000yr) and (1 km)/(1000 m)
2) Now convert 50 (km)/(Myr)to (cm)/(yr).5 (cm)/(yr)
proof
50 (km)/(Myr)= 50,000m/1,000,000yr=5,000,000cm/1,000,000yr=5cm/yr

Answer: 50 km/Myr= 5 cm/yr

Step-by-step explanation:

We know that 1 km = 1000 m

And 1m = 100 cm

Therefore, 1 km = 100,000 m

Also, 1 million = 1,000,000

Therefore, 1 km/ Myr=\(\frac{100,000\ cm}{1,000,000\ year}=\frac{1}{10}\ cm/yr\)

\(1km/Myr=\frac{1}{10}cm/yr\\\Rightarrow\ 50\ km/Myr=\frac{1}{10}\times50\\\Rightarrow\ 50\ km/Myr=5\ cm/yr\)

Hence, 50 km/ Myr = 5 cm/yr
