Answer:
<u> 3/4 km</u>
Step-by-step explanation:
<u>turn 3/4 km into a fraction first to compare it to 0.8 km</u>
which is 0.8 km and 0.75
- so the shorter distance is 3/4 km (0.75 km)
Each individual question has a prob of 1/2 of being correct so its
(1/2)(1/2) .... (1/2) --- (8 times)
= (1/2)^8
= 1/256
so the answer is 1/256
