1 mile = 1.61 km
1.86x10^5 miles = 1.61(1.86x10^5) km
1.86x10^5 miles/sec = 2.99x10^5 km/sec
= 1.80 x 10^7 km/min ----> multiplied by 60
= 1.08 x 10^9 km/hour ---> multiplied by another 60
1.86x10^5 miles = 1.61(1.86x10^5) km
1.86x10^5 miles/sec = 2.99x10^5 km/sec
= 1.80 x 10^7 km/min ----> multiplied by 60
= 1.08 x 10^9 km/hour ---> multiplied by another 60
