The Pioneer River is 1500 km long.
1500 m = 15,000 km
Thirty hours(30hours)
1500 m = 1.5 km
1500 km = 932.06 miles
1000 m = 1 km → 1500 m = 1500 ÷ 1000 km - 1.5 km → 10 km + 1500 m = 10 km + 1.5 km = 11.5 km
A km is 1000 meters, so 1500 meters is 1.5 km. 1500 meters is of greater distance.
1500 kilometers = 1.5 million meters 1500 m = 1.5 km
I do not think there any planets 1500 km from the sun only if it were 1500 million km from the sun , maybe there is a planet , but not 1500 km.
No because 1500 m = 1.5 km
1500 x 12 = 18,000 km in one year.
1500 cm = 15 meters 15 meters = 0.015 km
