It will take fran 0.67 hours to swim 1.8 mi upstream
it will take fran 0.25 hours to swim 1.8 mi downstream
<u>Step-by-step explanation:</u>
Fran's speed in still water= 5mph
speed of the river=2.3 mph
upstream journey
speed while swimming upstream= speed in still water-speed of the river=5-2.3=2.7mph
distance to be traveled upstream=1.8 miles
Time taken to swim= upstream distance/upstream speed
=1.8/2.7
=0.67 hours
Fran will take 0.67 hours to swim upstream
downstream journey
speed while swimming downstream= speed of Fran+speed of the river
=5+2.3=7.3mph
distance to be travelled downstream=1.8 miles
time taken=downstream distance/ downstream speed
=1.8/7.3=0.25 hours
6/8 chance should be the answer :)

Answer:
10
Step-by-step explanation:
Answer:
hee-hee
Step-by-step explanation:
We first have to find out how many possible outcomes are in total.
There are 2 outcomes for the coin, either that the coin reads heads or tails.
There are 6 outcomes for the die, from 1 to 6.
2 x 6 = 12
There are 12 possible outcomes.
Now let's move on to the favorable outcomes.
We want to get the coin to flip on either heads or tails, and that the die has a number greater than or equal to 6.
The coin can only flip heads or tails.
The die's sides only goes up to 6.
The probability that the coin reads head and tails and that the dices number is less than or equal to 6 is 12/12 or 1. It is certain.
hope this helps and hope this correct :)
