Question

The distance between Earth and Mars is 2.2253 $\times$ ${10}^8$ kms. The distance between Mars and Saturn is $1.19666\times {10}^9$ kms. A spaceship starts from Earth and flies to Saturn via Mars.
Find the total distance covered by the spaceship in metres.

• A. 1.41919x1012 m
• B. 14191900000
• C. 1419190000000
• D. 1.41919 $\times$ ${10}^9$ km

Answer 1

Answer: (A), (C), (D)

The correct options are
A 1.41919x1012 m
C 1419190000000
D 1.41919 $\times$ ${10}^9$ km

The total distance travelled by the spaceship between Earth and Saturn = Distance between (Earth & Mars + Mars & Saturn)
$=2.2253\times {10}^{8}kms+1.19666\times {10}^{9}kms=2.2253\times {10}^{8}kms+11.9666\times {10}^{8}kms=14.1919\times {10}^{8}kms=1.41919\times {10}^9\times {10}^{3}m=1.41919\times {10}^{12}m$
