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
I guess it would be true because 100+95+85+80 = 360, and there are 360 degrees in a circle.
Answer:
He traveled 140 miles after 4 hours.
Step-by-step explanation:
Two find the area of a triangle multiply the two sides together and then divide by 2. To find the area of a rectangle just multiply the two sides that are given and you will get the answer.
Answer:
55.5 km
Step-by-step explanation:
speed=distance/time
55.5= 333/6
