He fastest that a seahorse can travel is 2,640 feet per hour. what is its top speed in miles per hour?
0.05 miles per hour
0.2 miles per hour
0.5 miles per hour
2 miles per hour

Step-by-step explanation:

You get 2640 and double it which is 5280 and then do 2640/5280 which is 0.5, that is the amount of miles in 2640 feet. So the answer is 0.5 mph which is C

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

1/5^2 = 7.56/45
