1 time because 50 plus 50 is 100
It would be 0.35 because you need to multiply by 5 and then move the decimal 2 spaces to the right.
First multiply 9 by 60 to find feet/minute: 9x60=540. Multiply that answer by 60 to get feet/hour: 540x60=32400. Divide that by 5,280 to get miles/hour: 32400/5280=6.14 roughly :)
There would be 15 adults and 5 children in that group.
15 adults = $75
5 Children= $15
75+15= $90
150 because if it is going 420 in 14 hours you divide 420 by 14 which gives you 30 and then you multiply 30 x 5 and you get 150 so the bird goes 150 miles in 5 hours
